help: make option --help open man pages only for Git commands
If option --help is passed to a Git command, we try to open
the man page of that command. However, we do it for both commands
and concepts. Make sure it is an actual command.
This makes "git <concept> --help" not working anymore, while
"git help <concept>" still works.
