Maybe longlines-mode could provide a variable
"longlines-inserted-LF-are-hard" and then use it in an
after-change-functions hook to mark all inserted LF as hard when that
variable is non-nil.

I'd guess that the variable should be non-nil by default and only bound to
nil at a few specific spots, hopefully all of them in longlines.el.
