 In these functions, \code{nalloc} is the number of elements to
 allocate.  In \code{psArrayAlloc}, the value of \code{psArray.n} is
-initially set to zero.  Users may choose to restrict the data range
-after the \code{psArrayAlloc} function is called.  For
-\code{psArrayRealloc}, if the value of \code{nalloc} is smaller than
-the current value of \code{psArray.n}, then \code{psArray.n} is set to
-\code{nalloc}, the array is adjusted down to match \code{nalloc}, and
-the extra elements are dropped and freed if necesitated by the
-reference counter.  If \code{nalloc} is larger than the current value
-of \code{psArray.n}, \code{psArray.n} is left intact.  If the value of
-\code{array} is \code{NULL}, then \code{psArrayRealloc} must return an
