Comment(by hamish):

 If term 2 (element) is "file", trunk's libgis checks to see if the file
 already exists & insists on --overwrite. So for file input= and output=
 term 2 should probably stay as "file".  This also means that the GUI
 should use term 2 (element) to decide if there should be a file [Browse]
 button present, instead of term 3 (prompt/description) as it does now.

 term 1 remains "old", "new"; the value of "any" doesn't seem to be used
 any more in g6.4+ or g7.

 so that leaves the switch for deciding on a text input box to be based on
 the third term (prompt/description). (as far as
 gui/wxpython/gui_core/forms.py is concerned)

 so e.g. for r.in.mat we have this info from --interface-description
  <gisprompt age="old" element="mat" prompt="file" />

 `element` would go back to "file", and term 3, `prompt` (aka description),
 would change from "file" to "text" (or "bin" or generic "file").

 And the "or enter text interactively" box would be made to only show up if
 `prompt` was "text".

 In GRASS 6 with GRASS_UI_TERM set, the `prompt` term 3 is used in the
 "Enter the name of" line, as is term 1's "new". e.g. for r.in.bin it is
 {input}:
 {{{
 OPTION:   Binary raster file to be imported
      key: input
 required: YES

 Enter the name of an existing {input} file
 Hit RETURN to cancel request
 >
 }}}

 so having that be "text" or "binary" would still read well (although still
 locked to English).


 thoughts?
