Not sure if I got it right but attached patch is for the template of
patchwork that displays the patches (patch.html).  It adds a link back
to gmane to the displayed message id header field using gmane's
message id resolver (mid.gmane.org).  Thus one can jump back to the
thread in the mailing list with very little effort.
