Log:
  MFC   r268066:
  regex(3): Add support for \< and \> word delimiters
  
  Solaris and other OSs have support for \< and \> as word
  delimiters in utilities like sed(1). These are useful to
  have for general compatiblity with Solaris but should be
  avoided for portability with other systems, including the
  traditional BSDs.
  
  Bump __FreeBSD_version as this is likely to affect some
  userland utilities.
