lintian-explain-tags: Discrepancy between man page and --help message

This bug report concerns the lintian-explain-tags executable, in particular the --tags flag. According to the help message:

 -t, --tag, --tags display tag descriptions

And according to the man page:

 -t, --tag, --tags
           This option has no effect. It exists for historical reasons

Having tested it, the help message is correct.
