Ok, I see now.  Many commands are expected to work on the visual
representation, so only a few commands that incorrectly treat inserted
newlines should be fixed.  I see no problem in matching additional
newlines in `query-replace' and the regexp search, but I don't see
how to distinguish soft newlines inserted by longlines-mode and hard
newlines with the `hard' property using the regexp search, i.e. how
(re-search-forward "[ \t\n]") could find soft newlines and skip
hard newlines?
