+Verified with `allout-aberrant-container-p'. The usefulness of
+this check is limited to shallow depths, because the
+determination of aberrance is according to the mistaken item
+being followed by a legitimate item of excessively greater depth.
+
+The classic example of a mistaken item, for a standard allout
+outline configuration, is a body line that begins with an '...'
+ellipsis. This happens to contain a legitimate depth-2 header
+prefix, constituted by two '..' dots at the beginning of the
+line. The only thing that can distinguish it *in principle* from
+a legitimate one is if the following real header is at a depth
+that is discontinuous from the depth of 2 implied by the
+ellipsis, ie depth 4 or more. As the depth being tested gets
+greater, the likelihood of this kind of disqualification is
+lower, and the usefulness of this test is lower.
+
+Extending the depth of the doublecheck increases the amount it is
+applied, increasing the cost of the test - on casual estimation,
+for outlines with many deep topics, geometrically (O(n)?).
+Taken together with decreasing likelihood that the test will be
+useful at greater depths, more modest doublecheck limits are more
+suitably economical.")
