git alias and --help

I'm having a tiny question about git aliases.

in ~/.gitconfig I defined an alias

b = branch



This works well execp if I type


git b --help

Now I get the output
`git b' is aliased to `branch'


which is nice to know however what I reall wanted is to get the helptext
for the branch command.


Is there any trick to get the help text of git branch without
having to type

git branch --help
