That's awkward.  The obvious workaround is to keep prepending 0s until
you come up with a name that's not used.  But I'd rather not worry
about that unless someone actually runs into the problem.

If you can come up with an exact list of problems, preferably with
patches, that'd be nice.

/etc/group isn't portable.  "id" is usually the best.

It might be, yes (not that I'd like to spend my time implementing it :-).
Frankly I didn't follow your examples, though.
