Subject: [PATCH] contrib: script to setup git to pull a vendors branches

This simple script is intended to setup a new git configuration to
pull the branches and tags for a specific vendor.  This should
simplify some of the steps needed for working with a vendor's
branches.

	* git-fetch-vendor.sh: New file.
