Is this something we fixed last month?

    submodule: no [--merge|--rebase] when newly cloned
    
    "git submodule update" can be run with either the "--merge" or "--rebase"
    option, or submodule.<name>.update configuration variable can be set to
    "merge" or "rebase, to cause local work to get integrated when updating
    the submodule.
    
    When a submodule is newly cloned, however, it does not have a check out
    when a rebase or merge is attempted, leading to a failure.  For newly
    cloned submodules, simply check out the appropriate revision.  There is no
    local work to integrate with for them.
