Simplify the "takes no value" error path by relying on PARSE_OPT_NOARG being set correctly. That is:
- if the PARSE_OPT_NOARG flag is set, reject --opt=value regardless of the option type; - if the PARSE_OPT_NOARG flag is unset, accept --opt=value regardless of the option type.
This way, the accepted usage more closely matches the usage advertised with --help-all.
No functional change intended, since the NOARG flag is only used with "boolean-only" option types in existing parse_options callers.
