skeletons: better comments for some tables

Browse Source 
And also, remove the incorrect indentation of these comments:

    -  /* YYR2[YYN] -- Number of symbols on the right hand side of rule YYN.  */
    +/* YYR2[RULE-NUM] -- Number of symbols on the right-hand side of rule RULE-NUM.  */
     static const yytype_int8 yyr2[] =
     {
            0,     2,     4,     0,     2,     1,     1,     1,     3,     2,

I don't remember why this indentation was added (in
0991e29b75), but it seems wrong,
at least for yacc.c.  I suspect this was done with lalr1.cc (where
this is embeded in the class definition, so it should be indented),
but today lalr1.cc uses other routines to output these comments.

* data/skeletons/bison.m4 (b4_integral_parser_tables_map): Improve the
wording of the comments of some tables.
* data/skeletons/c.m4 (b4_integral_parser_table_define): Remove
indentation.
