	* iswitchb.el (iswitchb-use-virtual-buffers): Added support for
	"virtual buffers" (off by default), which makes it possible to
	switch to the buffers of recently files.  When a buffer name
	search fails, and this option is on, iswitchb will look at the
	list of recently visited files, and permit matching against those
	names.  When the user hits RET on a match, it will revisit that
	file.
	(iswitchb-read-buffer): Added two optional arguments, which makes
	isearchb.el possible.
	(iswitchb-completions, iswitchb-set-matches, iswitchb-prev-match,
	iswitchb-next-match): Added support for virtual buffers.
