I just filed a couple of glibc bugs against getopt; depending on the reaction I
get from the glibc folks, I may need to update gnulib's getopt accordingly.

At any rate, our unit tests have no testing of an optstring of "-:..."
or "+:..." (bug 11039 - glibc doesn't honor the : as a means of silencing
stderr and returning ':' instead of '?'), nor of the GNU extension of an
optstring of "W;" (bug 11040 - use of this extension mistakenly allows -; as a
valid short option). For that matter, we aren't really testing whether an
optstring of ":" effectively silences stderr and changes return value, even
without throwing the GNU extensions of leading '-' or '+' into the mix.
