OK, thanks for the suggestions.

The problem is that I may want to tag more files than the OS command
line length limit (ARG_MAX).  At least on my system, that's 128K,
which would limit me to tagging maybe 2000 files in one shot.  But I'd
like to add about 100~150 tags to various sets of files, and given
that each go-round takes about 30-40 seconds, if I can combine things
it would be ideal.  But I guess it doesn't really matter.
