In the kernel, we use "git diff --stat --summary" for exactly this reason.

Well, not exactly. 

The thing is, even if the file is _not_ empty, there's a huge difference 
between "added 100 lines to an already-existing file" and "created a new 
100-line file". Which is exactly what "--summary" adds. 

And it sometimes even makes sense to show the summary without the 
diffstat. If you're _only_ interested in create/delete/rename information, 
you can do "git show --summary <cmit>". It won't give you line counts, but 
it will give you information about any changes to filenames, eg in the 
kernel archive, you could see an example of this with

	git show -M --summary 95b482a8d31116f3f5c2a5089569393234d06385

where you have a combination of renames, creates and deletes.

So I think it's already better than what you ask for.
