[GRASS5] form and underscore

Hi,

Radim, nice, the CPU problem is solved now for
d.what.vect & form. Thanks for the fix!

Un/related: The column names do now show underscore
characters, but when I do copy-paste, they are there:

cat : 4672
id : 4813
f_code : AL020
nam : TRENTO
tile_id : 11
fac_id : 3389

Any idea for that (Tcl/tk problem?)?

Markus
