Sorry, I had a look at this and can see how it is related to the bug I
fixed, but can't see how, before the fix, the unhighlighting would have
happened, i.e. how space highlighted at the end of the document would have
been unhighlighted after inserting characters at EOB.
I suppose that would be the logic in the function
whitespace-empty-at-eob-regexp? I don't understand how regions are
un-highlighted in this mode/in font-lock, though.
