So I dug a little more deeply, and the problem is that the reflog for
master was getting updated, but not the reflog for HEAD, and that's
what "git reflog" was showing --- hence my confusion.

What are the rules for when HEAD's reflog should get updated, and is
this documented anywhere in the man pages?
