MODE_DIST (-s) is the same as MODE_DIST_LENVENSHTEIN (-ss) but much slower. Drop it. Make MODE_DIST_MYERS (-sss, faster than MODE_DIST_LENVENSHTEIN) take its place (-s). The original comment was incorrect (-s is not Eugene W. Myer's algorithm). It is correct now. Co-authored-by: eagleoflqj and Maskray
