Subject: [PATCH 3/3] Update git-pull to match updated git-fetch.

From: Junio C Hamano <[email-masked]>
Date: Thu, 18 Aug 2005 00:39:31 -0700

This retires the git-parse-remote script, and allows pull to fetch
from multiple remote references.  There is no support for resolving
more than two heads, so that would be next.

Signed-off-by: Junio C Hamano <[email-masked]>
