I have a fix to the article-id problem with control messages, which
I will broadcast as soon as our machine ("machaids") recovers from
some recent hardware problems.  The fix is to have expire not delete
from the history file the lines for control articles until after the
default expiration period is over.  Previously expire was deleting
these lines without checking their date of arrival.  Thus if the
control article came back after expire was run, it would be processes
as a new article.
