fast bug fix in bison

[Bamford, Harold]

Greetings,

 

There is a small typo in the latest released version of bison (1.30-1) in src/print.c:

 

  /* rule # : LHS -> RHS */
  fprintf (out, "\n%s\n", _("Grammar"));
  for (i = 1; i <= nrules; i++)
    /* Don't print rules disabled in reduce_grammar_tables.  */
    if (rlhs[i] >= 0)
      {
 fprintf (out, _("\nrule %-4d %s ->"), i, tags[rlhs[i]]);
 rule = &ritem[rrhs[i]];
 if (*rule > 0)
   while (*rule > 0)
     fprintf (out, " %s", tags[*rule++]);
 else
   fprintf (out, "  /* %s */\n", _("empty"));
      }

On line 234, where the rule is being printed, the leading "\n" is missing. This makes the *.output file almost unreadable.

 

Nice work on this program!
