(max, min): Make these functions, not macros; we'd like to pass them arguments that would be bad to evaluate more than once. (newline_cache_on_off): New function. (scan_buffer): New argument END. Call newline_cache_on_off. If this buffer's newline cache is enabled, consult it to see if we need to scan a region for newlines, and store information in the cache after doing so. (find_next_newline): Pass new arg to scan_buffer. (find_before_next_newline): New function.
