Re: [PATCH] Make cg-clone handle local directories as sources

cg-clone is described as only being used with remote repositories, but
it has the nice feature of creating the destination directory for you.

This patch adds two features:
        1. A destination directory can (optionally) be specified.
        2. The source directory can be in the local file system.

The following, for example, now works:

        cg-clone rsync://rsync.kernel.org/pub/scm/cogito/cogito.git
        mkdir test ; cd test
        cg-clone ../cogito ../cogito2/

(This version of the patch actually doesn't break existing
functionality.)
