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.

These talk about something else, which is partly outdated.

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.
