Update to 0.2:

0.2:

 * SYNOPSIS preprocessor lines use Fd.
 * Names found in the SYNOPSIS are remembered using Marc Espie's
   ohash library (bundled for compatibility with operating systems
   lacking it); that information is used subsequently to mark up
   function names with Fn, function arguments with Fa, type names
   with Vt, preprocessor macros with Dv.
 * Foreign function names are marked up with Xr.
 * Whitespace handling has been improved in many respects (blank
   lines in literal displays; re-wrap text lines; new sentence, new
   line; better horizontal spacing; no more whitespace at the end
   of lines).
 * Improved handling of closing punctuation.
 * Escaping of quotes at the beginning of macro arguments.
