Indeed, but if you do it from within jit-lock it will not work as
expected because jit-lock will mark the chunk just processed with
`fontified` == t.

Anything that runs "later" (i.e. after we exit `jit-lock-fontify-now`)
will work, but `pre-redisplay-function` means the display will only be
updated at the next redisplay, whereas with a timer we also force
a redisplay, thus shortening the time during which we display an
incompletely fontified chunk.
Jit-lock itself uses a similar timer for similar purposes.
We could make it slightly cheaper by exporting the `pending_funcalls` to
ELisp and then using it instead of a 0s timer.
