No, this is wrong as far as I recall.
I was solving the same problem before some time. Your solution (i.e.
git-diff-index --relative) only displays the changed files under a
subdirectory, which is incorrect when not in the repository root.

I solved the problem by writing a 50 line or so "ueberfunction" which
manually relativizes the paths returned by git-diff-index to the correct
form required by git-commit (i.e. relative to the current directory, no
matter what it is -- and still displaying all the changed files not only
under the current directory, but from the whole repository).  Seems to
work, but I don't really feel very "proud" of it so I haven't tried to
share it so far.
