Re: [PATCH v7 09/10] submodule-config: add subomdule config scope

> From: Matthew Rogers <mattr94@gmail.com>

> Before the changes to teach git_config_source to remember scope
> information submodule-config.c never needed to consider the question of
> config scope.  Even though zeroing out git_config_source is still
> correct and preserved the previous behavior of setting the scope to
> CONFIG_SCOPE_UNKNOWN, it's better to be explicit about such situations
> by explicitly setting the scope.  As none of the current config_scope
> enumerations make sense we create CONFIG_SCOPE_SUBMODULE to describe the
