For me, the most annoyance I've had with commits doing too much at once
comes later. Too common flavors are:

1. I bisect, but instead of finding one small commit making one change,
   the bisect lands on a giant change-the-world commit, giving very
   little bisect. (And for bonus nuisance, multiple bugs keep bisecting
   down to this same change-the-world commit.)

   Obviously, this patch isn't in that category.

2. I want to revert a change, but "git revert" isn't useful since the
   change of interest is tangled with other things.

   And maybe this second case isn't likely to happen in this case, (I
   imagine it's unlikely that other users of this function will show

It's clear you've thought through this. So your call if there's no easy
way to split this:
