commit 7a679909ff8c3ee3535e4ef218b50a28b788daa3
Author: G. Branden Robinson <g.branden.robinson@gmail.com>

    Fix documentation nits.
    
    * doc/groff.texi: Remove unnecessary paragraph break.  Wrap long line.
    
    * man/groff.7.man: Stop protecting ellipsis at end of sentence from
      end-of-sentence detection (it doesn't matter in this case since it
      also ends a paragraph [and section]), but it's a poor example to set.
    
    * man/groff_diff.7.man: Assert support of \D escape for AT&T troff
      commands (that they're not _perfectly_ compatible is covered in
      section "Implementation Differences").  Remove unnecessary paragraph
      break.  Fix spelling typo.  Fix missing-word typo.
