52d5733ff0 * data/lalr1.cc: Adjust the indentation of the labels. 
Use it.

a0e68930d8 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional 
argument, an informative message.
Call YY_SYMBOL_PRINT.
Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
* data/lalr1.cc (destruct_): Likewise.
In addition, no longer depend on b4_yysymprint_generate and
b4_yydestruct_generate to generate these functions, do it "by
hand".

e757bb10bc * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was 
invoked, yydestruct the lookahead.
* tests/calc.at (Calculator $1): Update the expected lengths of
traces: there is an added line for the discarded lookahead.
* doc/bison.texinfo (Destructor Decl): Some rewording.
Define "discarded" symbols.

284acc8ba7 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used. 
(YYDSYMPRINTF): Rename as...
(YY_SYMBOL_PRINT): this.
* data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
two.
Use it instead of direct symprint_ calls.
(yybackup): Tweak the "Now at end of input" case to match yacc.c's
one.
