`switch-to-buffer-other-window` sounds good, but we need to get rid of
`display-flag` (it makes no sense to call
`clone-indirect-buffer-other-window` with a nil value for
`display-flag` and `clone-indirect-buffer-other-window` should not call
`clone-indirect-buffer` with a non-nil `display-flag` because it wants
to be in charge of displaying the buffer).
