The refactor of the libvirt tools command parser introduced a bug where
the '--help' option would cause an error:
$ virsh list --help
error: command 'list' doesn't support option --help
rather than printing the help for the command as the help option is
supposed to be handled separately from the real options.
Re-introduce the separate handling to the new parser code.
