  The following adds /* <num> */ to dbg_line_numbers so there's the chance
to more easily lookup the ID of the match.pd line number used for
dumping when you want to debug a speicific replacement.  It also cuts
the lines down to 10 entries.

  static int dbg_line_numbers[1267] = {
        /* 0 */ 161, 164, 173, 175, 178, 181, 183, 189, 197, 195,
        /* 10 */ 199, 201, 205, 923, 921, 2060, 2071, 2052, 2058, 2063,
...

Queued for testing, will push.

	* genmatch.cc (define_dump_logs): Make reverse lookup in
	dbg_line_numbers easier by adding comments with start index
	and cutting number of elements per line to 10.
