on the list.

Your macro _name_ is misleading (and so would
be `in-other-window').  You're doing BODY with
the next-window's _buffer current_.  But you're
not _selecting_ the next-window while doing it.
IOW, that window isn't selected when you do BODY.

`with-selected-window' does its BODY with
its WINDOW selected.  You could (if that were
what you wanted) define a `with-other-window'
which did the equivalent for the `next-window':

(defmacro with-other-window (&rest body)
  `(with-selected-window (next-window) ,@body))
