  i realize that one of each commit is the simplest use case, but the
scenario that occurred to me is a bunch of branches being merged and,
suddenly, you have a bug, and you're not sure where it came from so
you identify a number of good commits, one per merged branch, and go
from there.

  also, making it clear you can have more than one good commit is
consistent with the synopses, which use ellipses to represent that
very thing.
