Fixed a number of issues relating to line wrapping.

- Extend CMARK_OPT_NOBREAKS to all renderers and add `--nobreaks`.
- Do not autowrap, regardless of width parameter, if CMARK_OPT_NOBREAKS
  is set.
- Fixed CMARK_OPT_HARDBREAKS for LaTeX and man renderers.
- Ensure that no auto-wrapping occurs if CMARK_OPT_NOBREAKS is enabled,
  or if output is CommonMark and CMARK_OPT_HARDBREAKS is enabled.
- Updated man pages.
