[PATCH v5 03/23] receive-pack: do not reuse old_sha1[] for other things

From: Junio C Hamano <gitster@pobox.com>

Message-ID: <1410819864-22967-4-git-send-email-gitster@pobox.com>
In-Reply-To: <1410819864-22967-1-git-send-email-gitster@pobox.com>

This piece of code reads object names of shallow boundaries, not old_sha1[], i.e. the current value the ref points at, which is to be replaced by what is in new_sha1[].
