It depends entirely on your glob(3) implementation since unlike
wu-ftpd, any port of the OpenBSD ftpd that doesn't include a private
glob.c will just use the one in your own libc.

We fixed a bunch of potential glob(3) problems in OpenBSD's glob.c
a while ago (though there may be more lurking--that is nasty code!).
