[PATCH 5/5] shortstatus: a new command

Add a new command that gives the status in
    XY PATH1 -> PATH2

format to be more machine readable than output from "git status", which is about previewing of "git commit" with the same arguments.

PATH1 is the path in the HEAD, and " -> PATH2" part is shown only when PATH1 corresponds to a different path in the index/worktree.

For unmerged entries, X shows the status of stage #2 (i.e. ours) and Y shows the status of stage #3 (i.e. theirs). For entries that do not have conflicts, X shows the status of the index, and Y shows the status of the work tree.

    X          Y     Meaning
    -------------------------------------------------
              [MD]   not updated
    M        [ MD]   updated in index
    A        [ MD]   added to index
    D        [ MD]   deleted from index
    R        [ MD]   renamed in index
    C        [ MD]   copied in index
    [MARC]           index and work tree matches
    [ MARC]     M    work tree changed since index
    [ MARC]     D    deleted in work tree
    D           D    unmerged, both deleted
    A           U    unmerged, added by us
    U           D    unmerged, deleted by them
    U           A    unmerged, added by them
    D           U    unmerged, deleted by us
    A           A    unmerged, both added
    U           U    unmerged, both modified
