Some fix-up might be needed if there's no x-spam-status header.

Another way is to `refile @. $msg' repeatedly, which effectively moves
the message to the end of the folder, and then `folder -pack'.  It has
the down-side of packing the folder but an abort part way through
shouldn't loose anything assuming refile is safe.

Another way is to anno(1) each message with a new field and then
sortm(1) on that.  But that leaves the annotation in place and anno
doesn't have a -remove option.
