-If \fIsortm\fR encounters a message without a date\-field, or if the
-message has a date\-field that \fIsortm\fR cannot parse, then \fIsortm\fR
-attempts to keep the message in the same relative position. This does
-not always work. For instance, if the first message encountered lacks
-a date which can be parsed, then it will usually be placed at the end
-of the messages being sorted.

-When \fIsortm\fR complains about a message which it can't temporally
-order, it complains about the message number \fIprior\fR to sorting.
-It should indicate what the message number will be \fIafter\fR sorting.
