It would be very useful to have a macro function
that writes a short message to the statistics line
(like Emacs does it on its message bar.) When
running background tasks it is often desirable
to provide completely unintrusive feedback, so
dialog() is not an option.
Nedit actually does that itself: if a macro runs
longer than a few seconds, the statistics line will
display the message "Macro Command in
Progress...". It would be handy if one could use
that feature from within a macro function to
provide arbitrary feedback.
