    * data/lalr1.jave: Update copyright years.
    (YYParser): Correct name of "generated from" file in Javadoc:
    use b4_file_name instead of @ofile@.
    (Location constructor): Correct Javadoc parameter name.
    (yylloc): Add missing opening m4 quote after b4_location_if.
    This removes a stray [ in the Javadoc of Lexer.getStartPos.
    (Lexer.yyerror): Fix incorrect m4 and Javadoc.
    (YYParser constructor): Correct Javadoc parameter name.
