Thanks.  Will typofix while extending with info supplied by Stefan
like so:

    submodules doc: update documentation for "." used for submodule branches

    4d7bc52b17 ("submodule update: allow '.' for branch value",
    2016-08-03) adopted from Gerrit a feature to set "." as a special
    value of "submodule.<name>.branch" in .gitmodules file to indicate
    that it signifies that the tracking branch in the submodule should
    be the same as the current branch in the superproject.

    Update the documentation to describe this.
