All raster modules are sensitive to the actual region settings. I just
have fixed r.line (io.c): G_set_window() should have been G_get_window().
Please try the updated version.

Please try v.bubble - should be an improved version of v.circle.
If v.bubble is the best, let's remove s.buffer and v.circle and rename
v.bubble to v.circle.

Thanks in advance!

Perhaps similar to s.to.vect bug?

Yes! Same thing with r.what/d.what.rast.
Or we decide that [rv].what are for script programming and
d.what.[vect|rast] are for interactive usage. Should get comparable module

Maybe we better implement "gdchart"?

v.slabel? I have added a note into TODO.

I think this is on the way for 5.1 (David, Radim?).

see above :-)
