It was my impression that --work-tree=.. was relative to the GIT_DIR. My 
tests seem to confirm that. Within the git work tree I do:

	echo "test">>COPYING

then

	cd .git/refs/heads
	git --work=tree=.. diff

and that produces a diff of COPYING showing the new line.

("man git" confused me about how WORK_TREE was supposed to work)

Ok, so if "is-inside-git-dir" then send a special "!" flag (and no 
dirtyState flags)? Does that seem reasonable?

Additionally, is it a good idea to echo the branch name when inside the 
git dir? That is, what does it "mean" to be on "master" when you're 
inside .git?

It seems like (psuedocode)...

	if git rev-parse --is-inside-git-dir; then
		use '!' flag to indicate caution

	elif git rev-parse --is-inside-work-tree; then
		proceed as before (with '*' and '+' flags)

	else
		do nothing

I think that handles those cases. No?
