Hi,

I made the experience that many people don't know that logging messages
(printed with `message') in the *Messages* buffer can be prevented with
binding `message-log-max' to nil.

Indeed, it's not easy to find in the doc, and the name `message-log-max'
also doesn't sound as if this variable could have this effect.

I think we should mention this effect of binding `message-log-max' to
nil in the docstring of `message', e.g. by changing this sentence:

The message also goes into the `*Messages*' buffer.

to

The message also goes into the `*Messages*' buffer if `message-log-max'
is not nil.


Thanks,

Michael.

How about adding:

(defsubst message-nolog (format-string &rest args)
  "Same as `message' except not writing to *Messages* buffer."
  (let (message-log-max) (apply 'message format-string args)))

This could encourage elisp authors to choose what to log to *Messages*
buffer. For example, ff-quiet-mode defaults to nil and, boy, this
library can write thousands of useless lines to *Messages* buffer.

I would appreciate something like that (besides improving the doc).

Maybe the same could be done for `with-temp-message'.


Regards,

Michael.
