xml2nroff: Fix issues pointed out by flake8.

This patch includes a few minor fixes pointed out by the flake8 tool. It drops an unused variable and the related imports, adds some blank lines where the PEP8 formatting standard indicates they should be, and does a comparison with None as "is None" instead of "== None".
