OK, fixed.  Thanks.

The doc string is OK.  The manual is misleading/incorrect, in this
regard: it speaks about a case where "the POSITION is a buffer
position".  This is wrong, as a buffer position in Emacs means a natural
number 1,2... (or a marker).  Maybe what should be said in this case is
that "POSITION represents a buffer position".  Its value cannot be
simply a buffer position, which is a number or a marker.
