That does sound like what I want.  I see that the indirect buffer does
not inherit the mode from either the original buffer nor from the
extension of the "new" buffer name.  Hmmm....  This might be useful.
I guess you could automate the creation so that the "right" major
mode is used.  I guess this is what's happening with the re-design
of Sweave.  I'll have to experiment.  Thanks
