I didn't understand that all the messages are identical, no matter
what triggered them.  If that's how we are going to implement them, it
indeed makes no difference which one you display.

To tell the truth, I don't like such vague warning, since the
reference to *Messages* is not specific enough to be useful, IMO.  It
is better to show some more specific text in the delayed warning
itself.
