[PATCH] show help message also for aliased commands
git help 'alias' currently only shows the actual git command
'alias' refers to. This patch changes the behavior so that
the help for the actual git command is shown. The user usually
knows the aliases defined, and sometimes its just more convenient
to type something like git help co than git help checkout
to find out about some rarely used option.
The original message is still there, so users do not face
unexpected or surprising behavior.
