As the doc string says:
---
(message FORMAT-STRING &rest ARGS)
[...]
In batch mode, the message is printed to the standard error stream,
followed by a newline.
---
I think that's a good default, but it would be nice if it could be
controlled.
While I was looking at all the compilation warnings, I would often do
"make 2> /tmp/warn" and look at that file, which does contain all the
warnings. However, it also contains the bits where we output
informational progress messages from Emacs, and that seems sub-optimal.
Would it be a good idea to have some way of specifying whether `message'
should output on stdout instead of stderr?
Like
(let ((standard-error 'stdout))
(message "This is not an error message"))
or... something.
