I don't see any need to add some weird `run-function` arg to
`cancel-timer`, here.

Why can't the repeat-map code offer a function to ... "programatically
terminate repeat-mode"?  Since it set up the timer, it can know what
function the timer will run and with what args and can thus run that
same code if it wants to.
