commit 146b0eafa17f0ac28f7ef3f273919c4c6a22f45b

    use -e rather than -d when checking for the existence of a subrepo
    
    The .git file in a submodule's root directory is not necessarily a
    directory, as is the case for the 'time' submodule.
    
    This fixes #7577, where some './sync-all' operations don't detect
    that the 'time' submodule is present in the repository.
