filter rework break about page

[Jason A. Donenfeld]

Oh. Right. That's the slow script I replaced, preferring instead markdown_py:
https://www.archlinux.org/packages/community/any/python-markdown/
That's the package you want.

I should include some documentation for this.

I will also soon recode that script to be pure python, instead of bash
shelling out to python. This will also allow inline syntax
highlighting.
