New Revision: 233132
URL: http://svn.freebsd.org/changeset/base/233132

Log:
  fts(3): Mention that FTS_NOCHDIR imposes {PATH_MAX} limits on the returned
  pathnames.
  
  With the current API (no *at functions), FTS_NOCHDIR requires that the
  fts_accpath start with the original path passed to fts_open(); therefore,
  the depth that can be reached is limited by the {PATH_MAX} constraint on
  this pathname.
