Thanks.  Once again, my proposal (and frankly, an expectation) was
that we provide a much simpler customization facility for grouping
entries in a tabulated-list-mode buffer.  I won't mind that the
current fancy customization is extended to use something like what
bufler.el does (although it needs to be generalize to support more
than buffer lists), but that will not fill the gap that I feel exists
in what we offer now.
