Yes, I don't want to change what git itself does with code, just what it
shows me when I run git diff to review a change before committing it. In
particular, I want that if I've wrapped a block around some code it
doesn't show lines where the only change is in its indentation, thereby
making it harder to spot actual changes.

Good idea.

It seems I could also set git.external to a script which calls diff -b,
but I can't work out if that just gets used by git diff or would also be
invoked by any internal operation where git needs a diff for its own use
(which I probably don't want, and might mess things up).
