Exposing the "long-lines" flag to Lisp is exactly what is needed.
So when lazy-highlight will detect a special value of a new
buffer-local variable when narrowing is in effect due to long lines,
then lazy-highlight can switch to a different algorithm
like you described earlier. Currently isearch-lazy-highlight-new-loop
checks for window-group-start and window-group-end. But when
the "long-lines" flag is set, it should also check for window-hscroll
because narrowed lazy-highlighting should be updated on hscrolling.
This "long-lines" flag will be also useful for pre-command-hook
and post-command-hook to convey the information about narrowing
to hooks.
