Imagine you did not have alias.aliasedinit in ~/.gitconfig but had a script called $(pwd)/searchpath/git-aliasedinit which we would fail to execute. What message would we get in that case? Currently I think we get permission denied.

Would we get the same with your patch, or something that does not hint at all that there is a permission problem?

See also the "tangent" part of
    http://thread.gmane.org/gmane.comp.version-control.git/171755

and the discussion that follows it. I do not think we reached any conclusion nor a patch.
