From 0e3c339bb69670b39161838de17f440480e1358a Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 15 Aug 2014 14:11:33 -0700 Subject: [PATCH] receive-pack: parse feature request a bit earlier Ideally, we should have also allowed the first "shallow" to carry the feature request trailer, but that is water under the bridge now. This makes the next step to factor out the queuing of commands easier to review.
