In the past "submodule.<name>.update=none" was an easy way
to selectively disable certain Submodules.

How would I do this with Git 2.14?

    submodule.<name>.active = false

My gut feeling is that all commands should respect the
"submodule.<name>.update=none" setting.

Well my gut feeling was that the "update" part of the name
reponds to the subcommand, not the generic action.

For example when you set update=none, git-status,
recursive git-diff still reported the submodule.
