commit a93ffb1ae972cb7be5d3788b460fce9a24b060d8
Author: Wayne Davison <wayne at opencoder.net>

    More non-breaking space/dash improvements
    
    - In html, use css more for non-breakability.
    - In nroff, mark more dashes as non-breaking in code->bold sections,
      and get rid of backslashed dashes in preformatted blocks.
