parse_options: accept multiple arguments

Browse source 
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.
