Improved escaping in commonmark renderer.

We try not to escape punctuation unless we absolutely have
to.  So, `)` and `.` are no longer escaped whenever they
occur after digits; now they are only escaped if they are
geuninely in a position where they'd cause a list item.

This required a couple changes to render.c.

- `renderer->begin_content` is only set to false AFTER a
  string of digits at the beginning of the line.  (This is
  slightly unprincipled.)
- We never break before a numeral (also slightly unprincipled).
