Thanks :)

Why do we not use this policy:

git-* is guaranteed to be the normal command without any strange alias
expansion, default parameters or something else a script does not like
to be changed in the commands. So all scripts use git-*, this will
prevent a double exec. The path to git-* should be obtained using git
--exec-path in the beginnig.

git <command> is to be used by the user if he wants aliases, default
parameters and other fancy stuff.

Using this policy the user can always get the normal behaviour and it
is possible to shadown built-in commands etc.
