argp-parse.c: ARGP_PARSE_ARGV0 shouldn't be ignored

[Gordon Matzigkeit]

Hi!

The current implementation of argp-parse.c makes ARGP_PARSE_ARGV0 do
nothing unless ARGP_NO_ERRS is specified.  This is undocumented, and I
don't know what a proper fix is, but the attached patch at least
returns an error code rather failing silently.

	* argp-parse.c (parser_init): Return ENOSYS if they specify
	ARGP_PARSE_ARGV0 without ARGP_NO_ERRS, rather than silently
	ignoring it.

Thanks,
