Speaking of pre-redisplay-functions, though, Stefan mentioned that it 
could be beneficial to do a debounce (based on 
buffer-chars-modified-tick?) because they can be called several times 
per user command.

Although if the parser short-circuits when the buffer is unchanged since 
last time, perhaps it's not necessary.
