Log message:
        When reducing initial empty rules, Bison parser read an initial
        location that is not defined.  This results in garbage, and that
        affects Bison's own parser.  Therefore we need (i) to extend Bison
        to support a means to initialize this location, and (ii) to use
        this CVS Bison to fix CVS Bison's parser.
        * src/reader.h, reader.c (epilogue_augment): Remove, replace
        with...
        * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
        * src/parse-gram.y: Adjust.
        (%initial-action): New.
        (%error-verbose): Since we require CVS Bison, there is no reason
        not to use it.
        * src/scan-gram.l: Adjust.
        * src/Makefile.am (YACC): New, to make sure we use our own parser.
        * data/yacc.c (yyparse): Use b4_initial_action.
