Makes sense.

So you did not find it utterly rude and presumptuous that somebody sent a
new iteration of your patch without even so much as consulting with you
whether you're okay with this? I salute your forbearance, then.

Besides, it is not really a better version of your patch. That would have
been:

As you can see, this is _actually_ building on your work rather than
replacing it.

But since that replacement made it into -rc1, I will stop spending brain
cycles on it.

Thank you for your contribution, I am glad that you keep sending patches
to the Git mailing list!
