True.  We are creating the config file for the new repository, so the
initial setenv() would make sense.  We _could_ save away end user's
GIT_CONFIG and restore it where you unsetenv() in your patch, but I do not
think it would buy us anything other than "be consistent with other
programs that misbehave when end user has GIT_CONFIG".  

Honestly, GIT_CONFIG is purely for scripts like git-svn that muck with
files that are in the config format to have a way to make sure that they
access the file they intend to, and being able to use GIT_CONFIG to keep
git programs from reading from $HOME/.gitconfig is primarily for giving
our test scripts repeatable environment, nothing more.

I think ignoring end-user GIT_CONFIG like this patch does, instead of
doing random nonsense, would be a good bugfix for "git clone".
