When submodule.$name.update is given as hint from the upstream in the .gitmodules file, we used to blindly copy it to .git/config, unless there already is a value defined for the submodule. However, there is no reason to expect that the update mode hinted by the upstream is available in the version of Git the user is using, and a really custom "!cmd" prepared by an upstream person running on Linux may not even be available to a user on Windows. It is simply irresponsible to copy the setting blindly and to attempt to use it during a later "submodule update" without validating it first. Just show the suggested value to the diagnostic output, and set the value to 'none' in the configuration, if it is not one of the ones that are known to be supported by this version of Git.
