Subject: [RFC, 03/10] create-pull-request: use git request-pull and arbitrary
	remotes
Date: Fri, 13 May 2011 23:37:27 -0000
From: Darren Hart <dvhart@linux.intel.com>
X-Patchwork-Id: 4003
Message-Id: <dda204962f3a3818351452fc0eae4c8364b685ae.1305329659.git.dvhart@linux.intel.com>
To: openembedded-core@lists.openembedded.org
Cc: Martin Jansa <martin.jansa@gmail.com>

Allow for arbitrary remotes via a new -u argument. Remove the hard coded
references to the pokylinux repositories. Create the WEB_URL from known
remotes. Future patches can add additional WEB_URL mappings for remotes
like Git Hub, Gitorious, and kernel.org.

Rather than duplicating the git request-pull command ourselves, just use
the existing one.
