Johannes Altmanninger f20e8e5860 alias: don't add --wraps for wrappers with the same name
These aliases seem to be common, see #7389 and others.  This prevents
recursion on that example, so `alias ssh "env TERM=screen ssh"` will just
have the same completions as ssh.

Checking the last token is a heuristic which hopefully works for most
cases. Users are encouraged to use functions instead of aliases.
