If you are going to remove it, "alias" it to something.
alternatively, I guess I'll make "git-whatchanged" binary to do it.
Can I ask what the problem is with it? The code is a mess I'm guessing.
I'd also suggest, instead of the message:
'git whatchanged' is nominated for removal. If you still use this command, please add an extra option, '--i-still-use-this', on the command line and let us know you still use it by sending an e-mail to <git@vger.kernel.org>. Thanks. fatal: refusing to run without --i-still-use-this
add to the message:
<run this instead>
love & respect, jcarr
