I figured if all you are doing is some setup and turning on a minor 
mode, it should be enough to only do once. A minor mode would generally 
track all subsequent modifications to the buffer with 
after-change-functions or the like (we don't bind 
(inhibit-modification-hooks t) while rendering the output, although it 
looks like we might, for a small extra speed boost).

But if that doesn't work for some reason, or doesn't cover all your 
goals, please feel free to install the patch.
