I was just being overly precise. I *did* fix the problem. But since it was
not my intention, I quoted the verb "fix".

The code does exactly that. It does even more: as `fixup! <SHA-1>` is
allowed (for SHA-1s that have been mentioned in previous `pick` lines), it
tries to match that before falling back to the incomplete prefix match.
