A warning when the option is used or a mention in the release notes.

I would tell her "Since 1.4.3 it has been a compatibility no-op and
our documentation made that clear, and by now based on a search nobody
seems to be using it".

What happened in 1.6.0, then?  Well, before 1.6.0, the git-am(1)
manual said

 -b, --binary
	Pass --allow-binary-replacement flag to git-apply (see
	git-apply(1)).

and the git-apply(1) manual said

 --allow-binary-replacement, --binary
	Historically we did not allow binary patch applied
	without an explicit permission from the user, and this
	flag was the way to do so.  Currently we always allow binary
	patch application, so this is a no-op.

Afterwards, the entry in the git-am(1) manual was removed, saving the
reader a little time.
