lowdown: patch to fix macOS and UTF-8 bugs

Browse Source 
- Improve UTF-8 handling by not treating bytes >=0x80, which tend to be
  UTF-8 continuation bytes, as control characters.

  This leaves control characters U+0080 through U+009F in the output
  (incorrectly) but doesn't mangle other UTF-8 characters, so it's a net
  win.

  See: https://github.com/kristapsdz/lowdown/pull/140

- Don't output a newline between a `.SH` and a heading.

  This fixes `makewhatis` output on macOS and (as a result) `man`
  completions for `fish` on macOS.
