Parsing of --restrict-file-names option is not consistent with WGET, accepts one option only , and not comma-separated combinations .

The flags should be ORed after verifying incompatibilities (unix vs windows or lowercase vs uppercase), but it should accept , for example, --restrict-file-names=windows,lowercase -> that works in wget, not in wget2 .
