Thanks!
The handling of overlapping areas is the reason I keep recompiling the
older version of v.buffer as v.oldbuffer. This lets me use the old debug
flag to prevent it from cleaning the areas, which I can then turn into
discrete areas instead of having them combined by the newer version.
Which reminds me, since the latest upgrade ...

So: how do I reassign the cats so there are 47 instead of 1
in the buffer?
# get rid of the old
v.category type=centroid op=del
# create some new sequential ones
v.category type=centroid op=add cat=1 step=1
(cat= is the number it starts counting from)
if you need the cat to match the seed point, use v.distance as earlier
suggested. and do beware of what becomes of overlapping areas.
