Thank you, Junio, for taking the time to reply to this!

Absolutely agreed. It occured to me as I lied down to sleep that
this fix could quite possibly have repercussions. And it's been in
my head all the walk to my work this morning. I ended up thinking
about it in this way:

If GIT_DIR is exported by git-sh-setup and we can assure that
git-sh-setup gets it right, then it's effectively the same as if the
user had set it explicitly, before calling the shell script: all
external commands called by the shell script will have GIT_DIR set
appropriately in all cases then.

The only problem I see now is when an external command (or the shell
script) can't properly deal with GIT_DIR being set, but then that's
a whole different bug.

I understand you're worried about this, but I can't really see
specifics, now having thought about this for a bit.

Oh yeah, and I've been meaning to look into that for a long time.
Sigh.
