I am a little lukewarm on my patch if only because of the precedent it
sets.  There are a trillion options that revision.c parses that are not
necessarily meaningful or implemented for sub-commands that piggy-back
on its option parser. I'm not sure we want to get into manually
detecting and disallowing each one in every caller.

I tend to agree with your final sentiment there. But the point that
users may not realize that blame already follows is also valid. Perhaps
we should catch --follow, as in your patch, but instead of saying that
it's an unknown argument, just print out a helpful message saying blame
already follows renames (and then continue with the blame anyway, so
as to not set a precedent to abort on unknown-but-currently-accepted
flags).

Sure, that would probably make sense. Care to roll a patch with
suggested wording?
