Re: Idle timers with the active minibuffer

[Richard Stallman]

            * keyboard.c (command_loop_1): Handle non-number values of
            `minibuffer-message-timeout'.

That change seems to be needed for this:

        ;; Save the original value of `minibuffer-message-timeout', and
        ;; set it to nil so that isearch's messages don't get timed out.
        isearch-original-minibuffer-message-timeout minibuffer-message-timeout
        minibuffer-message-timeout nil)

Without the change in keyboard.c, won't sit_for crash
given nil as an argument?
