Can we fix things so that we're not at glibc's mercy, even there?
We could preprocess the regular expression [A-Z], and turn it into
[ABCDEFGHIJKLMNOPQRSTUVWXYZ], before we hand it off to glibc.
POSIX would allow this behavior, and users would prefer it.

This could be done in a gnulib module, so that other GNU programs
could also use the fix.
