What I meant was "restarted during run of the handler". I wanted to show
the difference between the two timers: the idle timer is restarted
_always_, but the spell timer may or may not be restarted, depending on
circumstances. Of course the timer may be started from another place,
otherwise it wouldn't be possible to run it again once it stopped.

The spell timer must be restarted when there is something new to check
spelling of. I suppose it's done from idle timer because it's
convenient: the idle timer is always running and it's in one place.

That would mean the timer runs while there is something to do, then
stops and is never started again, which is obviously wrong. The timer
will have to be started from other parts of code, when the "right"
conditions are recreated (or maybe just started unconditionally; it
will stop immediately if there is nothing to do, anyway). Don't ask me
what the "other parts" are; I don't know that .-)
As for the spell timer, the right place to restart it could be
ScInputHandler::KeyInput or ScTabViewShell::KeyInput.
