New Revision: 261493
URL: http://svnweb.freebsd.org/changeset/base/261493

Log:
  Implement the '!' operator for files* files. It means 'include this
  only if the specified option is NOT specified.' Bump version because
  old config won't be able to cope with files* files that have this
  construct in them.
