Consistently quote, like `GIT_DIR`, here?

Likewise.  We may probably want to say `--work-tree=<path>` inside a
bq pair, and definitely `GIT_WORK_TREE` inside a bq pair.

This is the best part of this patch, I would think.  But you said
<path> in the "if" part of this "if--then", so (unless your Git
magically can read users' minds some magic), I'd expect to see the
same <path> to appear somewhere in the "then" part.

	If you just want to run git as if it was started in `<path>`
	then use `git -C <path>`.

perhaps?
