XEmacs at least has a cache mapping (line number -> newline location), invalidated on significant buffer changes. Whether it's worthwhile in this day and age I'm not sure: it may be faster to scan for nearby newlines (probably both in the L2 cache if referenced recently) than to maintain the line-start cache; and distant lines won't be in that cache anyway.
