parse_options: accept multiple arguments
Allow command-line options to accept multiple arguments without additional quoting by taking the list of arguments until one starting with a "-" is reached. The only current use of this is the --pkg option in makepkg. This allows (e.g.) makepkg --pkg foo bar and packages "foo" and "bar" will be built.
