Subject: [PATCH] git-svn: don't sanitize remote names in config

From: Eric Wong <[email-masked]>
Date: Sat, 28 Jun 2008 20:40:32 -0700

The original sanitization code was just taken from the
remotes2config.sh shell script in contrib.

Credit to Avery Pennarun for noticing this mistake, and Junio
for clarifying the rules for config section names:
