Personally, my opinion is that if we're going to print the message at
all, the names used for the message should match the names used in the
code.  So -1 from me on calling it immediate in the code but smoothed
in the message.  On the other hand, I have no personal attachment to
that message, so if other people feel it's not needed at all, I could
see removing it.
