After restarting Emacs, I now can't reproduce it either.

My previous session had been running for a couple of months, at least.
I installed a few new packages and did a lot of messing around in
*scratch*, so perhaps one of those activities modified the way C-u
works and I just didn't notice for a while.  Hard to imagine how that
could happen by accident, though.
