I was wondering if anybody was using git alias outside git repository, as
I thought such a use would be somewhat unorthodox.  The easter egg took 6
days to get discovered.

I'll commit this on 'master'.  Thanks for satisfying my curiosity ;-)

[PATCH] Accept git aliases outside a git repository

af05d67 (Always set *nongit_ok in setup_git_directory_gently(),
2008-03-25) had a change from the patch originally submitted that resulted
in disabling aliases outside a git repository.

It turns out that some people used "alias.fubar = diff --color-words" in
$HOME/.gitconfig to use non-git command outside git repositories, and this
change broke such a usage, so this resurrects the support.
