Re: 23.0.50; assert arguments warning

[Richard Stallman]

       (eval-when-compile (require 'cl))
       (let ((end 1)(pos 2))
         (assert (<= pos end) t "p=%s e=%s" pos end))

    This gives a warning

       my-file.el:32:42:Warning: `error' called with 4 args to fill 2 format
         field(s)

That error seems correct.  You gave t for SHOW-ARGS, so it put
`pos' and `end' into the `error' call automatically.  Then you
added `pos' and `end' yourself.  That makes 4 format args,
but just two %s to display them.

I wonder if SHOW-ARGS is not properly documented.  Did you misunderstand
its meaning?
