Messages
========
The `message' function will show the user a small message (typically
no more than a single column of text). In graphical applications it
_won't_ bring up a separate window, only displaying the text in a
status bar or something similar. In a console-based environment, the
message will be printed to the `stderr' stream, followed by a line
break.
- Function: message #!optional display-now
Displays a one-line message, the string MESSAGE. If DISPLAY-NOW,
every effort will be made to display the message as soon as
possible, possibly before the next scheduled screen update (if
applicable).
This function is exported by the `rep.system' module.
