From 5d46c9d41febe5fe85f94f7db2b190d8abf1e71e Mon Sep 17 00:00:00 2001
From: Daniel Barkalow <barkalow@iabervon.org>
Date: Sat, 12 May 2007 11:46:03 -0400
Subject: Add handlers for fetch-side configuration of remotes.

These follow the pattern of the push side configuration, but aren't
taken from anywhere else, because git-fetch is still in shell.
