Subject: [v3 PATCH 2/2] remote add: add a --no-tags (-n) option

From: Samuel Tardieu <[email-masked]>
Date: Tue, 20 Apr 2010 01:31:31 +0200

Add '--[no-]tags' options to 'git remote add' which add the
'remote.REMOTE.tagopt = --[no-]tags' to the configuration file.
This mimics the "--tags" and "--no-tags" options of "git fetch".
