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.

Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:

It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:

  http://docutils.sourceforge.net/

Use the Makefile in this directory to generate the man and HTML pages.
