bitmap_list_string() is very ineffective when printing bitmaps with long
ranges of set bits because it calls find_next_bit for each bit in the
bitmap. We can do better by detecting ranges of set bits.
In my environment, before/after is 943008/31008 ns.
I would add a couple of words, maybe in parentheses, to describe what

+ buf = number(++buf, end, rtop - 1, default_dec_spec);
++buf is a bit confusing here. Since you will rewrite the buf value
anyway, I would write the parameter as buf + 1.
Agree, it's sloppy. I'll send the patch by tomorrow.
