You probably used GCC and therefore missed that this patch removes the
last user of `short_opt()`, and therefore leaves `short_opt()` unused.
Apparently Clang v9.1.0 (which is used in Azure Pipelines' macOS builds)
is smart enough to notice that, though. So please squash this in when you
send another iteration of this patch (in a hopefully smaller package than
that six-and-a-half-dozen patch series):
