	I see no reason to abuse quit-window for what’s essentially
	switching to a buffer to edit one.  That is: the
	eww-restore-history call right after quit-window edits the
	/current/ buffer.  Thus, it indeed makes sense to explicitly use
	set-buffer before that.  (Or to wrap the call in
	with-current-buffer, anyway.)

	Moreover, vc.el already uses a dedicated buffer-local variable
	for a similar purpose, and so does rcirc.el, and perhaps a few
	more modes out there.
