O(nlogn) Algorithm - Find three evenly spaced ones within binary string
...le, S may be 110110010, where n=9. It has evenly spaced 1s at positions 2, 5, and 8.
Scan S left to right, and make a list L of positions of 1. For the S=110110010 above, we have the list L = [1, 2, 4, 5, 8]. This step is O(n). The problem is now to find an arithmetic progression of length 3 in L,...

... a number when they are created so you can have a list that looks like 1 2 5 if you delete buffers. This is a bit awkward, yes, and that makes switching to a buffer by its number a bit too troublesome. Prefer switching by partial name, :b foo<Tab> or cycling, :bn :bp.
