I thought that that winner-mode would handle this as requested, but
doing `M-x winner-mode' first and doing `C-x <left>' instead of `C-x 4
b' doesn't work either: it only changes the window-buffer
correspondence so that there are still 3 windows.  Maybe winner-mode
should advise the describe-* functions, or with-output-to-temp-buffer,
to DTRT.  (If so, print-help-return-message should have a clause to
detect winner-mode, and display the winner-undo key binding instead of
switch-to-buffer-other-window.)
