Concerning sortfold -- I vaguely remember some e-mail in past
yarn-list digests that explains how yarn decides that 2 messages
are duplicates. It certainly does not do a byte by byte comparison,
e.g., fx /b. I believe it checks the headers in some manner or other
and uses one of the header lines to decide which message to delete.
Perhaps others know the details.
