Changes (by pv):

  * status:  new => closed
  * resolution:  => fixed


Comment:

 Fixed in r6970

 The range was also extended to negative degrees and orders for which
 either
 v>-m-1 OR v<m.

 The easiest way to go forward would perhaps to just implement the whole
 function via hyp2f1, handling the boundary cases specially.
