    Request relative paths when getting git patches (closes bgo#611744)
    
    Git by default gives all paths as relative to the repository base
    directory, which breaks our current vc patching machinery. This patch
    changes our git backend to ask for relative paths, fixing invocations of
    Meld on git-versioned files while in subdirectories (e.g., cd src; meld
    ./foo.c instead of meld src/foo.c).
