Gah. Lacking any more input, I was going to clean this up and re-submit,
but it seems to fail some unrelated tests.

It appears that with this patch, you can no longer do:

  cd .git && git show HEAD

because of some awful ordering constraints in the wrapper. Specifically,
looking in the config for pager.* entails calling git_path, which ends
up calling setup_git_env, which says "I guess our git_dir is '.git'".
Which is of course totally wrong, and calling setup_git_directory would
find the right thing.

So the logic in setup_git_env seems bogus, but should basically never be
invoked because we do generally call setup_git_directory_gently before
then. Either it should probably call setup_git_directory_gently (though
I am afraid of what awful side effects that could have), or it should
just barf, and people should do setup_git_directory beforehand (and I'm
sure that will break something too).

Blargh.
