[PATCH] help: show help for aliases

[Tom Kunze <mail@tom-kunze.de>]

If an alias is a single git command show the man page of the
aliased git command with --help.

Hi,

I noticed that when I pass --help to an alias which is only a git
command it tells me a information about the alias. But it would be
nice if it instead opens the corresponding man page of the command.

There is a memory leak but in my opinion it can be ignored because
the process will be replaced anyway.

Regards,
Tom Kunze
