Hmm... I seem to understand.  TransposeFrame uses the buffer of the
window it splits so there you have a lot of windows showing the frame's
selected window initially and eventually see them set to their original
buffers.  We want to set a window's final buffer immediately at the time
of splitting.

Note that TransposeFrame also may revert the cdr of the list it deals
with.  Back then the 'above and 'left values for SIDE were not known
yet.

I'll attach a capture of the "initial" split and the "final" split after
a couple of invocations of 'transpose-frame'.
