Fair enough, another example could be if you wanted to allow specifying
a custom log file for whatever reason, one could make -L/--log have an
optional argument to specify what file to output the log to, and if no
argument is given use the default log file that makepkg currently

The existing code is built around checking for and removing one trailing
character from an option, it'd require both more code change and more
code all-around to deal with checking for the same character either once
or twice than to just check for a different single trailing character.
