New Revision: 274924
URL: https://svnweb.freebsd.org/changeset/base/274924

Log:
  Consider the negation operator (!) to be a word even if it is not followed
  by whitespace.  This allows "optional !foo" which is what most programmers
  are naturally going to tend to do as opposed to "optional ! foo".
