After b), you now have to wait 2 seconds (jit-lock-antiblink-grace)
before you get the old behaviour (string-fontifying 7-10). Previously,
you would get it after 0.5 seconds (jit-lock-context-time). It's
arguable that the new behaviour is worse than the old one, for the
specific case where you already expected lines 7-10 to be temporarily
invalidly fontified anyway. (I say "invalid" because the user's
intention is to move up to line 3)
Anyway, I think it's a pretty minor thing, but I wanted to record it for
completeness.

OK.
I will also add the "set marker buffer to nil" optimization that Alan
suggested.
If there's no further comments, I will push this to master in a day or
so.
