svn commit: r291861 - head/share/man/man9

New Revision: 291861

Log:
  style.9: Add a small blurb about allowing bool
  
  It was allowed before, but make it very explicit it is allowed now.  And
  prefer 'bool' to older types that were used for the same purpose -- int and
  boolean_t.
  
  Like with the C99 fixed-width types, use common sense when changing old
  code.
  
  No igor regressions.
