I've played around with this idea a little bit in pg's pg-status
command but I most likely do not have all cases covered.

In general I try to show HEAD<-->index first using uppercase letters
then index<-->working directory second in lowercase letters.

Here's the critical portion of pg-status:

	git-diff-index --cached --name-status HEAD | sed -e 's/ / /'
	if test $index_only  = n
	then
	  git-diff-files --name-status | sed \
		-e 's/      / /' \
		-e 's/^D /g /' \
		-e 's/^M /m /' \
		-e '/^U /d'
	  pg--ls-others | sed 's/^/x /'
	fi

Thus far I've found it useful to behave this way and I haven't run
up against any states which didn't make immediate sense to me.
Here's the documentation I have in pg-status describing what it
can show:

Status indicators (displayed in column 1):

 A : New file has been marked for addition with pg-add.
 D : Existing file has been marked as deleted with pg-rm.
 M : Existing file has been modified (and is known to the index).
 U : File still has unmerged hunks, see pg-resolved.

 m : Existing file (maybe) has been modified (use -q to know for sure).
 g : File has been removed from directory but not marked with pg-rm.
 x : File is not known to repository and isn't being ignored.
