Re: Can't interrupt directory_files_internal run fromtimer-event-handler

    BTW, `while-no-input' and `throw-on-input' are not documented on the
    Emacs Lisp Reference; and the docstring for `throw-on-input' is
    suboptimal:

while-no-input is in the Lisp manual.  throw-on-input is not for users
to use; perhaps we should rename it to while-no-input-throw-internal.
