Hi Raymond,
It's not a new string. If you hadn't it in the strings to translate, it's surely because it has already been. There was a missing space in the original text that had been corrected yesterday ( I can't find the bug report right now). This is why it reappears untranslated.
In Transifex, picking the previous translated text in your language among the suggested ones might fit. There is a icon at the bottom right of the suggested string to see what are the modifications. You'll see that it is almost the same.

Cheers,
Harrissou

How come this huuuuuge string has suddenly appeared in QGIS application 
(and in transifex for translation) so shortly for the 2.6 release???

<h4><a name="re">Overview</a></h4>⏎
<p>A "delimited text file" contains data in which each record 
starts on a new line, and ⏎
is split into fields by a delimiter such as a comma. ⏎
This type of file is commonly exported from spreadsheets (for example 
CSV files) or databases. ⏎
Typically the first line of a delimited text file contains the names of 
the fields. ⏎
</p>⏎
<p>⏎
Delimited text files can be loaded into QGIS as a layer. ⏎
The records can be displayed spatially either as a point⏎
defined by X and Y coordinates, or using a Well Known Text (WKT) 
definition of a geometry which may⏎
describe points, lines, and polygons of arbitrary complexity. The file 
can also be loaded as an attribute⏎
only table, which can then be joined to other tables in QGIS.⏎
</p>⏎
<p>⏎
In addition to the geometry definition the file can contain text, 
integer, and real number fields. By default ⏎
QGIS will choose the type of field based on its the non blank values of 
the field. If all can be interpreted⏎
as integer then the type will be integer, if all can be interpreted as 
real numbers then the type will⏎
be double, otherwise the type will be text.⏎
</p>⏎
<p>⏎
QGIS can also read the types from an OGR CSV driver compatible 
"csvt" file. ⏎
This is a file alongside the data file, but with a "t" 
appended to the file name. ⏎
The file should just contain one line which lists the type of each field. ⏎
Valid types are "integer", "real", 
"string", "date", "time", and 
"datetime". The date, time, and datetime types are treated as 
strings in QGIS.⏎
Each type may be followed by a width and precision, for example 
"real(10.4)".⏎
The list of types are separated by commas, regardless of the delimiter 
used in the data file. An⏎
example of a valid format file would be:⏎
</p>⏎
⏎
<pre>⏎
"integer","string","string(20)","real(20.4)"⏎
</pre>⏎
⏎
<h4><a name="creating">Creating a delimited text layer</a></h4>⏎
<p>Creating a delimited text layer involves choosing the data file, 
defining the format (how each record is to⏎
be split into fields), and defining the geometry is represented. ⏎
This is managed with the delimited text dialog as detailed below. ⏎
The dialog box displays a sample from the beginning of the file which 
shows how the format⏎
options have been applied.⏎
</p>⏎
<h5>Choosing the data file</h5>⏎
<p>Use the "Browse..." button to select the data file. Once 
the file is selected the⏎
layer name will automatically be populated based on the file name. The 
layer name is used to represent⏎
the data in the QGIS legend. ⏎
</p>⏎
<p>⏎
By default files are assumed to be encoded as UTF-8. However other file⏎
encodings can be selected. For example "System" uses the 
default encoding for the operating system. ⏎
It is safer to use an explicit coding if the QGIS project needs to be 
portable.⏎
</p>⏎
<h5>Specifying the file format</h5>⏎
<p>The file format can be one of⏎
<ul>⏎
<li>CSV file format. This is a format commonly used by spreadsheets, in 
which fields are delimited⏎
by a comma character, and quoted using a "(quote) character. Within 
quoted fields, a quote⏎
mark is entered as "".</li>⏎
<li>Selected delimiters. Each record is split into fields using one or 
more delimiter character.⏎
Quote characters are used for fields which may contain delimiters. 
Escape characters may be used ⏎
to treat the following character as a normal character (ie to include 
delimiter, quote, and ⏎
new line characters in text fields). The use of delimiter, quote, and 
escape characters is detailed <a href="#csv">below</a>.⏎
<li>Regular expression. Each line is split into fields using a 
"regular expression" delimiter.⏎
The use of regular expressions is details <a href="#regexp">below</a>.⏎
</ul>⏎
<h5>Record and field options</h5>⏎
<p>The following options affect the selection of records and fields from 
the data file</p>⏎
<ul>⏎
<li>Number of header lines to discard: used to ignore header lines at 
the beginning of the text file</li>⏎
<li>First record has fields names: if selected then the first record in 
the file (after the discarded lines) is interpreted as names of fields, 
rather than as a data record.</li>⏎
<li>Trim fields: if selected then leading and trailing whitespace 
characters will be removed from each field (except quoted fields). </li>⏎
<li>Discard empty fields: if selected then empty fields (after trimming) 
will be discard. This ⏎
affects the alignment of data into fields and is equivalent to treating 
consecutive delimiters as a ⏎
single delimiter. Quoted fields are never discarded.</li>⏎
<li>Decimal separator is comma: if selected then commas instead of 
points are used as the decimal separator in real numbers. For⏎
example <tt>-51,354</tt> is equivalent to -51.354.⏎
</li>⏎
</ul>⏎
<h5>Geometry definition</h5>⏎
<p>The geometry is can be define as one of</p>⏎
<ul>⏎
<li>Point coordinates: each feature is represented as a point defined by 
X and Y coordinates.</li>⏎
<li>Well known text (WKT) geometry: each feature is represented as a 
well known text string, for example⏎
<tt>POINT(1.525622 51.20836)</tt>. See details of the <a 
href="#wkt">well known text</a> format.⏎
<li>No geometry (attribute only table): records will not be displayed on 
the map, but can be viewed⏎
in the attribute table and joined to other layers in QGIS</li>⏎
</ul>⏎
<p>For point coordinates the following options apply:</p>⏎
<ul>⏎
<li>X field: specifies the field containing the X coordinate</li>⏎
<li>Y field: specifies the field containing the Y coordinate</li>⏎
<li>DMS angles: if selected coordinates are represented as 
degrees/minutes/seconds⏎
or degrees/minutes. QGIS is quite permissive in its interpretation of 
degrees/minutes/seconds.⏎
A valid DMS coordinate will contain three numeric fields with an 
optional hemisphere prefix or suffix⏎
(N, E, or + are positive, S, W, or - are negative). Additional non 
numeric characters are ⏎
generally discarded. For example <tt>N41d54'01.54"</tt> is a valid 
coordinate.⏎
</li>⏎
</ul>⏎
<p>For well known text geometry the following options apply:</p>⏎
<ul>⏎
<li>Geometry field: the field containing the well known text 
definition.</li>⏎
<li>Geometry type: one of "Detect" (detect), 
"Point", "Line", or "Polygon".⏎
QGIS layers can only display one type of geometry feature (point, line, 
or polygon). This option selects⏎
which geometry type is displayed in text files containing multiple 
geometry types. Records containing⏎
other geometry types are discarded. ⏎
If "Detect" is selected then the type of the first geometry in 
the file will be used.⏎
"Point" includes POINT and MULTIPOINT WKT types, 
"Line" includes LINESTRING and⏎
MULTLINESTRING WKT types, and "Polygon" includes POLYGON and 
MULTIPOLYGON WKT types.⏎
</ul>⏎
<h5>Layer settings</h5>⏎
<p>Layer settings control the way the layer is managed in QGIS. The 
options available are:</p>⏎
<ul>⏎
<li>Use spatial index. Create a spatial index to improve the performance 
of displaying and selecting spatial objects.⏎
This option may be useful for files larger than a few megabytes in 
size.</li>⏎
<li>Use subset index. Create an index if a subset of records is being 
used (either by explicitly setting a subset string ⏎
from the layer properties dialog, or an implicit subset of features for 
which the geometry is valid in files⏎
for which all not geometries are valid). The index will only be created 
when a subset is defined.</li>⏎
<li>Watch file. If this options is selected QGIS will watch the file for 
changes by other applications, and ⏎
reload the file when it is changed. The map will not be updated until 
refreshed by the user, but indexes and⏎
extents will be reloaded. This option should be selected if indexes are 
used and it is likely that another⏎
application will change the file. </li>⏎
</ul>⏎
⏎
<h4><a name="csv">How the delimiter, quote, and escape characters 
work</a></h4>⏎
<p>Records are split into fields using three character sets: ⏎
delimiter characters, quote characters, and escape characters. ⏎
Other characters in the record are considered as data, split into⏎
fields by delimiter characters. ⏎
Quote characters occur in pairs and cause the text between them to be 
treated as a data. Escape characters cause the character following them 
to be treated as data. ⏎
</p>⏎
<p>⏎
Quote and escape characters cannot be the same as delimiter characters - 
they⏎
will be ignored if they are. Escape characters can be the same as quote 
characters, but behave differently⏎
if they are.</p>⏎
<p>The delimiter characters are used to mark the end of each field. If 
more than one delimiter character⏎
is defined then any one of the characters can mark the end of a field. 
The quote and escape characters ⏎
can override the delimiter character, so that it is treated as a normal 
data character.</p>⏎
<p>Quote characters may be used to mark the beginning and end of quoted 
fields. Quoted fields can ⏎
contain delimiters and may span multiple lines in the text file. If a 
field is quoted then it must⏎
start and end with the same quote character. Quote characters cannot 
occur within a field unless they⏎
are escaped.</p>⏎
<p>Escape characters which are not quote characters force the following 
character to be treated as data. ⏎
(that is, to stop it being treated as a new line, delimiter, or quote 
character). ⏎
</p>⏎
<p>Escape characters that are also quote characters have much more 
limited effect. They only apply within quotes and only escape 
themselves. For example, if ⏎
<tt>'</tt> is a quote and escape character, then the string⏎
<tt>'Smith''s Creek'</tt> will represent the value Smith's Creek.⏎
</p>⏎
⏎
⏎
<h4><a name="regexp">How regular expression delimiters work</a></h4>⏎
<p>Regular expressions are mini-language used to represent character 
patterns. There are many variations⏎
of regular expression syntax - QGIS uses the syntax provided by the <a 
href="http://qt-project.org/doc/qt-4.8/qregexp.html">QRegExp</a> class 
of the <a href="http://qt.digia.com">Qt</a> framework.</p>⏎
<p>In a regular expression delimited file each line is treated as a 
record. Each match of the regular expression in the line is treated as 
the end of a field. ⏎
If the regular expression contains capture groups (eg <tt>(cat|dog)</tt>)⏎
then these are extracted as fields. ⏎
If this is not desired then use non-capturing groups (eg 
<tt>(?:cat|dog)</tt>).⏎
</p>⏎
<p>The regular expression is treated differently if it is anchored to 
the start of the line (that is, the pattern starts with <tt>^</tt>).⏎
In this case the regular expression is matched against each line. If the 
line does not match it is discarded⏎
as an invalid record. Each capture group in the expression is treated as 
a field. The regular expression⏎
is invalid if it does not have capture groups. As an example this can be 
used as a (somewhat ⏎
unintuitive) means of loading data with fixed width fields. For example 
the ⏎
expression⏎
<pre>⏎
^(.{5})(.{10})(.{20})(.{20})⏎
</pre>⏎
<p>will extract four fields of widths 5, 10, 20, and 20 characters from 
each line. ⏎
Lines less than 55 characters long will be discarded.⏎
</p>⏎
⏎
⏎
<h4><a name="wkt">How WKT text is interpreted</a></h4>⏎
<p>⏎
The delimited text layer recognizes the following ⏎
<a href="http://en.wikipedia.org/wiki/Well-known_text">well known 
text</a> types - ⏎
<tt>POINT</tt>, <tt>MULTIPOINT</tt>, <tt>LINESTRING</tt>, 
<tt>MULTILINESTRING</tt>, <tt>POLYGON</tt>, and <tt>MULTIPOLYGON</tt>. ⏎
It will accept geometries with⏎
a Z coordinate (eg <tt>POINT Z</tt>), a measure 
(<tt>POINT M</tt>), or both (<tt>POINT ZM</tt>).⏎
</p>⏎
<p>⏎
It can also handle the PostGIS EWKT variation, in which the geometry is 
preceded by an spatial reference ⏎
system id (eg <tt>SRID=4326;POINT(175.3 41.2)</tt>), and a variant 
used by Informix in which the WKT is ⏎
preceded by an integer spatial reference id (eg <tt>1 
POINT(175.3 41.2)</tt>).⏎
In both cases the SRID is ignored.⏎
</p>⏎
⏎
⏎
⏎
<h4><a name="attributes">Attributes in delimited text files</a></h4> ⏎
<p>Each record in the delimited text file is split into fields representing⏎
attributes of the record. Usually the attribute names are taken from the 
first⏎
data record in the file. However if this does not contain attribute 
names, then they will be named <tt>field_1</tt>, <tt>field_2</tt>, and 
so on. ⏎
Also if records have more fields than are defined in the header record 
then these⏎
will be named <tt>field_#</tt>, where # is the field number (note that 
empty fields at the end of a record are ignored).⏎
QGIS may override ⏎
the names in the text file if they are numbers, or have names like 
<tt>field_#</tt>,⏎
or are duplicated.⏎
</p>⏎
<p>⏎
In addition to the attributes explicitly in the data file QGIS assigns a 
unique ⏎
feature id to each record which is the line number in the source file on 
which⏎
the record starts. ⏎
</p>⏎
<p>⏎
Each attribute also has a data type, one of string (text), integer, or 
real number.⏎
The data type is inferred from the content of the fields - if every non 
blank value⏎
is a valid integer then the type is integer, otherwise if it is a valid 
real⏎
number then the type is real, otherwise the type is string. Note that 
this is⏎
based on the content of the fields - quoting fields does not change the 
way they⏎
are interpreted.⏎

⏎
<h4><a name="python">Using delimited text layers in Python</a></h4>⏎
<p>Delimited text data sources can be creating from Python in a similar 
way to other vector layers.⏎
The pattern is:⏎
</p>⏎
<pre>⏎
from PyQt4.QtCore import QUrl, QString⏎
from qgis.core import QgsVectorLayer, QgsMapLayerRegistry⏎
⏎
# Define the data source⏎
filename="test.csv"⏎
uri=QUrl.fromLocalFile(filename)⏎
uri.addQueryItem("type","csv")⏎
uri.addQueryItem("delimiter","|")⏎
uri.addQueryItem("wktField","wkt")⏎
# ... other delimited text parameters⏎
layer=QgsVectorLayer(QString(uri.toEncoded()),"Test CSV 
layer","delimitedtext")⏎
# Add the layer to the map⏎
if layer.isValid():⏎
QgsMapLayerRegistry.instance().addMapLayer( layer )⏎
</pre>⏎
<p>This could be used to load the second example file above.</p>⏎
<p>The configuration of the delimited text layer is defined by adding 
query items to the uri.⏎
The following options can be added⏎
</p>⏎
<ul>⏎
<li><tt>encoding=..</tt> defines the file encoding. The default is 
"UTF-8"</li>⏎
<li><tt>type=(csv|regexp|whitespace)</tt> defines the delimiter type. 
Valid values are csv, ⏎
regexp, and whitespace (which is just a special case of regexp). The 
default is csv.</li>⏎
<li><tt>delimiter=...</tt> defines the delimiters that will be used for 
csv formatted files, ⏎
or the regular expression for regexp formatted files. The default is , 
for CSV files. There is⏎
no default for regexp files.</li>⏎
<li><tt>quote=..</tt> (for csv files) defines the characters used to 
quote fields. The default is "</li>⏎
<li><tt>escape=..</tt> (for csv files) defines the characters used to 
escape the special meaning of the next character. The default is 
"</li>⏎
<li><tt>skipLines=#</tt> defines the number of lines to discard from the 
beginning of the file. The default is 0.</li>⏎
<li><tt>useHeader=(yes|no)</tt> defines whether the first data record 
contains the names of the data fields. The default is yes.</li>⏎
<li><tt>trimFields=(yes|no)</tt> defines whether leading and trailing 
whitespace is to be removed from unquoted fields. The default is no.</li>⏎
<li><tt>maxFields=#</tt> defines the maximum number of fields that will 
be loaded from the file. ⏎
Additional fields in each record will be discarded. The default is 0 - 
include all fields.⏎
(This option is not available from the delimited text layer dialog 
box).</li>⏎
<li><tt>skipEmptyFields=(yes|no)</tt> defines whether empty unquoted 
fields will be discarded (applied after trimFields). The default is 
no.</li>⏎
<li><tt>decimalPoint=.</tt> specifies an alternative character that may 
be used as a decimal point in numeric fields. The default is a point 
(full stop) character.</li>⏎
<li><tt>wktField=fieldname</tt> specifies the name or number (starting 
at 1) of the field containing a well known text geometry definition</li>⏎
<li><tt>xField=fieldname</tt> specifies the name or number (starting at 
1) of the field the X coordinate (only applies if wktField is not 
defined)</li>⏎
<li><tt>yField=fieldname</tt> specifies the name or number (starting at 
1) of the field the Y coordinate (only applies if wktField is not 
defined)</li>⏎
<li><tt>geomType=(auto|point|line|polygon|none)</tt> specifies type of 
geometry for wkt fields, or none to load the file as an attribute-only 
table. The default is auto.</li>⏎
<li><tt>subset=expression</tt> specifies an expression used to identify 
a subset of the records that will be ⏎
used.</li>⏎
<li><tt>crs=...</tt> specifies the coordinate system to use for the 
vector layer, in a format accepted by 
QgsCoordinateReferenceSystem.createFromString (for example 
"EPSG:4167"). If this is not ⏎
specified then a dialog box may request this information from the user⏎
when the layer is loaded (depending on QGIS CRS settings).</li>⏎
<li><tt>subsetIndex=(yes|no)</tt> specifies whether the provider should 
build an index to define subset during the initial file scan. The index 
will apply both for explicitly defined subsets, and for the implicit 
subset of features for which the geometry definition is valid. By 
default the subset index is built if it is applicable.</li>⏎
<li><tt>spatialIndex=(yes|no)</tt> specifies whether the provider should 
build a spatial index during the initial file scan. By default the 
spatial index is not built. </li>⏎
<li><tt>watchFile=(yes|no)</tt> specifies whether the provider should 
use a file system watcher to monitor for changes to the file.</li>⏎
<li><tt>quiet=(yes|no)</tt> specifies whether errors encountered loading 
the layer are presented in a dialog box (they will be written to the 
QGIS log in any case). The default is no. This option is not available 
from the GUI</li>⏎
</ul>⏎
⏎
