 Recursive push

 This command executes git-cpush recursively. It starts with
 the innermost submodules and then works its way back. Only accepts
 two levels of submodules. The push is only executed if all 
 submodules are on remote-tracking branches.

 Usage:
    git rpush ...

    ...: same arguments as git-push

    exit 0;

    cat >&2 <<EOF
 Warning: Untracked files in submodules. Add them to .gitignore
  in the respective submodules or remove them.
  Use "git status" to see where they are.
  Continuing anyway...
