No, the user is waiting because Emacs hasn't replied yet. > Idle timers are for when the user hasn't given any command, so Emacs is > waiting, rather than the user. You said "_defer_ fontification when the user is waiting for Emacs". When user is waiting for Emacs, idle timers won't run, and therefore fontifications done in a function that runs off an idle timer will not be performed. How does this not fit what you describe? > >> The 1st redisplay also only redrew the portion that was modified, which > >> is pretty close in many cases to the portion that later gets fontified. > > I was thinking about scrolling with C-v, in which case the first > > redisplay redraws almost the entire window. > > Same difference: the 1st redisplay redraws almost the whole window, and > the second as well because almost none of the text had been > fontified earlier. The amount of redrawing depends on what portions of the visible text are fontified.
