Re: git-diff on touched files: bug or feature?

Yes.  Very much so, intentionally, from very early days of git.
This serves as a reminder to the user that he started editing
but changed his mind to end up with the same contents as the
original, until the next "update-index --refresh" (which is
internally invoked from "status").

It would be nice to have a way to refresh a single file though. For
instance in vc-git.el the workfile-unchanged-p function currently has
to rehash the file every time to see if it really changed, because we
can't afford to refresh the whole project at that point.
