this simplifies the setup a lot, and avoids weird looking `./file.md` links showing up. it also does not show regular URLs any more. currently the command reference only has few of them, and not showing them in the offline documentation is hopefully not a big deal. instead of building more special-case solutions, clumsily preprocessing the input, or issuing verbal rules on dealing with URLs, should better be solved sustainably by not rendering relative links in `lowdown`: https://github.com/kristapsdz/lowdown/issues/105
