Rmail calls buffer-swap-text too much.  Related discussions concluded
    that this is unnecessary and introduces potential bugs and maintenance
    headaches.  See this message and the rest of its thread for the
    related discussions:

I did this for some low-level functions when I finished up the
Rmail-mbox code.  It would be nice to clean up some more
in the same way,
