Make parse_options_step() report PARSE_OPT_NON_OPTION instead
of PARSE_OPT_DONE to the caller, when it sees a non-option argument.
This will help implementing a nonstandard option syntax that
takes more than one parameters to an option, e.g.
-L n1,m1 pathspec1 -L n2,m2 pathspec2
by directly calling parse_options_step(). The parse_options() API
only calls parse_options_step() once, and its callers are not affected
by this change.
