getopt_long_only() seems to have a *feature* that you can abbreviate
options as long as they remain unambiguous. The point of long options is
convenience (well, and offering more options than getopt() can with the
Portable Character Set).

Why?

Anyway, since each option takes a mandatory argument, it shouldn't be that
hard to check if the command line carries an even number of arguments, and
then to process the arguments in pairs. Check the first component of each
pair with strcmp() against each supported option. Or set up a sorted array
and use bsearch(), for ultimate overkill.

.... getopt_clip() might be what you want; I don't know if it's available
on GNU/Linux.
