Make menu_rebuild conditional on whether the URL of a Views Page or Feed display has changed

Often times, I have had to change a few settings on a View that has a Page or Feed display, but not change the URL of the Page or Feed. This can be frustrating, since to save a View with a Page or Feed display appears to force a menu_rebuild so that the URL path for the display can be registered.

Thus, I propose that the menu_rebuild be made conditional. This could be done, I think, by temporarily saving what the old path was in a variable & then doing a comparison - something like:

if($old_url != $new_url) {
menu_rebuild();
}

I think this would make views saves much faster in many cases & would be much appreciated :)
