I didn't think to look at a modern BSD (the relevant function is
name_uid in pax/cache.c). Either way, any tar should be able to cope
with either output, assuming no system has the pathological case of a
user account with a numeric name different from its uid, but a blank
string seems to be more POSIX-correct.

There's another tar (possibly actually called bsdtar) in
contrib/libarchive that I couldn't make heads or tails of (it uses some
kind of modular design and I couldn't find the real implementation of
everything)
