I'm going to put the onus on you for this bikeshed to test it, and see
how you like it. I have tried have the other function, and I felt this
one looked better. Though I assume I have to fix the rebase error that
Chris pointed out anyway. So I'll do a v3 with the separate function
*after* you confirm you really want it. Otherwise, you'll just get the
rebase fail fix.
