It's possible.

I don't think it's worth the trouble, no: it's a kind of bug that can be
fairly hard to track down, and there's a non-negligible chance that in
the end the error is in that old `aggresssive-indent-mode` code, so the
motivation to spend the time on it is quite low.

It's not like we don't have enough other bugs to fix ;-)
