(SNAKE_LIMIT): New macro; merely documents already-used number 20. (diag): New `minimal' arg; all callers changed. Put results into struct partition. Apply `too_expensive' heuristic. Tune. (compareseq): New `minimal' arg; all callers changed. Tune. (shift_boundaries): Improve heuristic to also coalesce adjacent runs of changes more often.
