When the message is not cleared, it will be displayed until another message
will replace it.  This is unrelated to multi-message feature.

This is another misunderstanding.  I didn't intend to have this
on the release branch.  But since you mentioned it, why not?
Maybe better to apply the patch for clear-message-function
on the release branch?
