Optimize S_find_first_nonspace.
We were needlessly redoing things we'd already done.
Now we skip the work if the first nonspace is greater
than the current offset.
This fixes pathological slowdown with deeply nested
lists (#255). For N = 3000, the time goes from over
17s to about 0.7s.
Thanks to @mity for diagnosing the problem.
