-;;; #### SJT I'd really like this function to have just two hooks: (1) the
-;;; buffer filter list and (2) a sort function list. Both should be lists
-;;; of functions. Each filter takes two arguments: a buffer and a model
-;;; buffer. (The model buffer argument allows selecting according to the
-;;; mode or directory of that buffer.) The filter returns t if the buffer
-;;; should be listed and nil otherwise. Effectively the filter amounts to
-;;; the conjuction of the filter list. (Optionally the filter could take a
-;;; frame instead of a buffer or generalize to a locale as in a specifier?)
-;;; The filtering is done this way to preserve the ordering imposed by
-;;; `buffer-list'. In addition, the in-deletion argument will be used the
-;;; same way as in the current design.
-;;; The list is checked for length and pruned according to least-recently-
-;;; selected. (Optionally there could be some kind of sort function here,
-;;; too.)
-;;; Finally the list is sorted to gutter display order, and the tab data
-;;; structure is created and returned.
-;;; #### Docstring isn't very well expressed.
+;;; #### SJT would like this function to have a sort function list. I
+;;; don't see how this could work given that sorting is not
+;;; cumulative --andyp.
