configure_added_submodule always writes an explicit submodule.<name>.active
entry, even when the new path is already matched by submodule.active
patterns. This leads to unnecessary and cluttered configuration.
Introduce a single helper to centralize wildmatch-based pattern lookup.
In configure_added_submodule, wrap the active-entry write in a conditional
that only fires when that helper reports no existing pattern covers the
submodule’s path.
