In Documentation/gitattributes.txt, it says that you can suppress
diffs by setting the attribute "-diff", and you can override the
binary detection with the attribute "diff".
Make it work.

Evidently, this is on top of "next" + the funcname patches, since
I realized it only when working on top of them.
However, it should also apply cleanly to "master", and even
"maint". (The only reason I'm not doing it right now, is that I am
in the middle of preparing a patch pair, and doing this patch was
easy enough with rebase -i.)
