Doc suggestion for `cursor-type' in buffer.c

[Ben North]

The docstring for the variable `cursor-type' ends with the text

   When the buffer is displayed in a nonselected window,
   this variable has no effect; the cursor appears as a hollow box.

which suggests the user has no control over the cursor when in a
non-selected window.  In fact the user can control this, by means of the
variable `cursor-in-non-selected-windows'.  Would a patch like the below
(made against CVS 1.571) clarify the docstring?

Ben.
