Author: pfg Date: Sun Aug 3 18:39:11 2014 New Revision: 269484 URL: http://svnweb.freebsd.org/changeset/base/269484 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.
