[GRASS-user] v.digit snapping to close polygons

Hi,

Before I file this as a wish, I just want to make sure that I'm not doing
something wrong:

In v.digit (not the wx version - don't have access to that currently),
snapping works great for continuing lines, etc. However, whenever I draw a
boundary which I would like to be closed so that it can become an area,
snapping is inactive, i.e. I can put my ending vertex as close as I want
to the beginning vertex, they still stay separate. I know I can then move
the vertex and thus close the boundary (snapping works fine for the "move
vertex" operation), but this is an extra step, and can become quite
tedious.

So:

1) Am I doing something wrong ?
2) If not, would it be very difficult to make snapping work also for
closing boundaries in the current (gis.m) version of v.digit ?
3) Does this work in the wxgrass digitizer ?

long-standing bug(?) in v.digit...

yes, should work in wxgui vector digitizer...
