Adds a "?" suffix that can be used to indicate that an option's argument is optional. This allows options to have a default behaviour when the user doesn't specify one, e.g.: --color=[when] being able to behave like --color=auto when only --color is passed Options with optional arguments given on the command line will be returned in the form "--opt=optarg" and "-o=optarg". Despite that not being the syntax for passing an argument with a shortopt (trying to pass -o=foo would make -o's argument "=foo"), this is done to allow the caller to split the option and its optarg easily Signed-off-by: Ethan Sommer <e5ten.arch@gmail.com> Reviewed-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
