From 33736ea75f5e27e1137abbe3dfedf856c064b7ef Mon Sep 17 00:00:00 2001

Subject: [PATCH] Tweak auto-accept: * does not apply to NOTICE (as those may
 well be automated) * mirrors +g behaviour so that no useless accept entries
 are added for services * respects max_accept, if it would be exceeded the
 message is dropped with numeric 494 * check moved up so this is checked
 before floodcount/tgchange

Pulled from Charybdis upstream changeset 1388:b1ef26176350 done by jilles.
