contrib/workdir: add a simple script to create a working directory
Add a simple script to create a working directory that uses symlinks to point at an exisiting repository. This allows having different branches in different working directories but all from the same repository. Based on a description from Junio of how he creates multiple working directories[1]. With the following caveat: "This risks confusion for an uninitiated if you update a ref that is checked out in another working tree, but modulo that caveat it works reasonably well."
