timer.el questions

[Juanma Barranquero <lektu@terra.es>]

Two quiestions about timer.el:

1.- `timer-set-time' and `timer-set-time-with-usecs' say "if optional
     argument DELTA is a non-zero integer, blah blah blah" and then both
     do:

    (aset timer 4 (and (numberp delta) (> delta 0) delta))

    and there's a ChangeLog entry from Richard:

    1996-01-31  Richard Stallman  <rms@mole.gnu.ai.mit.edu>

        (timer-set-time, timer-set-time-with-usecs): Allow floating DELTA.  

    so, should the documentation be fixed to say "a non-zero number"?

2.- It is `timer-set-time-with-usecs' used anywhere on planet Earth, or
    it is just a case of creeping featuritis? Because the Emacs source
    does not use it, and a search on Google (web and group search) did
    not find anything but a few references to the timer.el source and to
    documentation...
