What I meant was that the current implementation gives very contrived
semantics.  The test in

(with-current-buffer buffer
  (with-selected-window window
    (eq (current-buffer) buffer)

succeeds unless `window' was not selected and did not display `buffer'
at the time `with-selected-window' was entered.
