Ok, but if I don't get to say anything about repurposing, can I at least
make it an error message instead of just spewing out the "invalid
option" help?

Subject: [PATCH] git-am: error out when seeing -b/--binary

The --binary option to git-apply has been a no-op since 2b6eef9 (Make
apply --binary a no-op., 2006-09-06) and was deprecated in cb3a160
(git-am: ignore --binary option, 2008-08-09).

We could remove it outright, but let's be nice to people who still
have scripts saying 'git am -b' (if they exist) and tell them the
reason for the sudden failure.
