I meant these > messages: > http://lists.gnu.org/archive/html/emacs-devel/2014-10/msg00705.html This message of yours seems to be talking about the problem I'm referring to above. At least, the way I read it, it seems to say that `input-pending-p' can return nil even if there is pending input (because that pending input is still in the system's input queue). If that's the case, we should have a bug report about that. > http://lists.gnu.org/archive/html/emacs-devel/2014-10/msg01039.html > http://lists.gnu.org/archive/html/emacs-devel/2014-10/msg01055.html These talk about something else, which is partly outdated. > I don't see the special case of zero discussed back there, so perhaps > this is a different problem. That's because the code has changed since. Now redisplay (which happens after running a command) is skipped based on the value of `input-pending-p' at the beginning of the *command*, rather than based on its value at the beginning of redisplay. And jit-lock.el has been changed to use (not (input-pending-p)), but only if jit-lock-defer-time is 0, so the special case for 0 is new. Stefan
