Log Message:
-----------
If messages are shown and output is printed without a pager, display
a heads-up on stderr at the end because otherwise, users may easily
miss the messages: because messages typically occur while parsing,
they typically preceed the output.  This is most useful with flag
combinations like "-c -W all" but may also help in some unusual
error scenarios.
Inconvenient ordering of output originally pointed out by espie@
for the example situation that /tmp/ is not writeable.
