From bb1119acca3f0735ca57871015d499d2358c9fb2 Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Sat, 17 Jan 2004 00:30:35 +0000 Subject: Fix for a signing bug when the mid wraps. Found by Fran Fabrizio . Add to the *start* of the list not the end of the list. This ensures that the *last* send sequence with this mid is returned by preference. This can happen if the mid wraps and one of the early mid numbers didn't get a reply and is still lurking on the list. Jeremy.
