STUF correction

[Rankin, Robert L]

I was trying to type from memory the reference to the paper "The History
and Development of Siouan Positionals with special attention to
polygrammaticalization in Dhegiha", and my lousy German got the
publication title wrong in spite of the available acronym.  STUF is
"Sprachtypologie und Universalienforschung."  I separated too many words
and put the wrong ending on Forschung I think.  Sorry 'bout that.  The
page ref. is Vol. 57, issue 2&3, pp. 202-227.  More than you ever wanted
to know (but short of a totally complete treatment, of course) about
Siouan positionals.
