commit: properly consider file include and exclude options when closing branch

It looks like this is meant to prevent adding another commit that does nothing
but close a branch on top of a commit that already closed the branch.  The
matcher building functions want `Dict[bytes, Any]`, not `Dict[str, Any]`, which
was found by adding type hints to the matcher related methods in scmutil.
