[GRASS5] [bug #3277] (grass) d.vect.thematic fails with DOUBLE

[Michael Barton]

I could add the regex line markers, but have no idea how I can test this in
the situation Maciek reports. How do you get a <double precision double
precision> column??? Maybe someone else could add these and test it for
me???

note the type is: 

<double precision 
double precision> 


I think the problem is thus:

# check column type
COLTYPE="`v.info -c $GIS_OPT_map [...] | grep $GIS_OPT_column | [...]


If you have a column PROD and another column with "PROD" in it, e.g.
PROD2, the grep step will pick out both.

Try using the regex start of line and end of line markers to refine the
search: 

... | grep ^"$GIS_OPT_column"$ | ...
