New Revision: 209030
URL: http://svn.freebsd.org/changeset/base/209030

Log:
  In dtrace lexer, do not unput token if it is EOF.
  
  This is harmless with OpenSolaris fex and yacc, but with FreeBSD
  causes '\xff' symbol to be physically put into input buffer, causing
  subsequent syntax error.
  
  MFC after: 1 week
