buffers.  The function should return a new list of live buffers,

typically by filtering its second argument in some way.

Default buffer-list-filters include:

`all'           All buffer names

`fallback'      A special case used to fallback to the

                original (non-ido/iswitchb) Emacs command.

                `fallback' isn't actually a buffer-list-filter

                itself, but can be used in

                `wg-buffer-list-filter-order-alist' just the

                same.

Becomes workgroup-local when set with `wg-set-workgroup-parameter'.

Becomes session-local when set with `wg-set-session-parameter'."

  "Alist defining the order in which filtered buffer-lists are presented.

The car of each entry should be the symbol of the original Emacs

command (not the ido or iswitchb remappings) -- i.e. one of

`switch-to-buffer', `switch-to-buffer-other-window',

`switch-to-buffer-other-frame', `kill-buffer', `next-buffer',

`previous-buffer', `display-buffer', `insert-buffer',

`read-buffer', or the special symbol `default', which defines the

buffer-list-filter order for all commands not present in this

alist.

The cdr of each entry should be a list of buffer-list-filter

identifiers defining the order in which filtered buffer-lists are

presented for the command.  See
