I don't understand the difference between the above and the application
of font-lock-multiline properties which you seem to have tried and rejected.
I don't necessarily disagree with your rejection of font-lock-multiline:
it can have disastrous effect indeed if the multiline region becomes large.

I guess I simply do not understand what you propose. Any improvement in
the multiline handling is welcome, but beware: this is not an easy area.

FWIW, I do pretty much exactly the above loop in smerge-mode and
I haven't heard complaints yet.

Find the current version attached. Consider it as 99.9% untested
code, tho. Also you need to eval it before you can byte-compile it.
And I strongly recommend you byte-compile it to reduce the
specpdl usage.
