Yeah, me too, but probably because I never needed it ;) Anyway, there were some discussions on this before [1]. I thin a viable workaround is using ls-files and grep. Quick example:

git diff -- $(git ls-files | grep -Ev "(^Documentation|^compat/mingw.c)")

would show everything except the whole Documentation subtree and mingw.c from compat. Now, you might even whip that into your very own shellscript or use a git alias (dirty):

[alias]
  ediff = "!sh -c 'git diff -- $(git ls-files | grep -Ev $0)'"

And call it with 
  git ediff "(Documentation|compat/mingw.c)"

Greetings, Jojo
