This isn't a simple refactor; the semantics of the new function are
different from the replaced code. I'd love to see a separate patch which
changed the semantics and described why that was necessary before a
refactor patch, so that we can compare the two versions in
place. Failing that, a description of the complete change would be
useful in evaluating this patch.
