Minor problem with calc-quit

[Slawomir Nowaczyk]

Hello,

When quitting calc (using calc-quit, i.e. "q") I get an error:

setq: Wrong type argument: stringp, nil

The following patch makes the error go away, but I have no idea if
this is the right fix:

diff -c "c:/Emacs/lisp/calc/calc.el" "c:/temp/buffer-content-4808WrC"

!           (delete-windows-on kbuf))
          (bury-buffer buf)
          (bury-buffer calc-trail-buffer)
          (and kbuf (bury-buffer kbuf))))))

          (bury-buffer buf)

          (and kbuf (bury-buffer kbuf))))))
