[RP] Swap behavior request and thanks for the RPWS changes.

[jbaber]

Hello, all,

  Tiny feature request: When there are only two frame visible, C-t x
ought to just swap them no questions asked.  What else could the user
mean?

  Tomm Smith: the RPWS changes will be of use to at least me once it
finally makes its way downstream into the standard repositories.  Thank
you.

 Sincerely yours,
   John B.
