Comment:

 Here is a doctest.  The dependence on #13712 is because the test is
 inserted directly after the one there.

 Points 2 and 3 have in my opinion been answered in comment:1.  Point 1
 (the result could be simplified more nicely) is something that should be
 done in Maxima (simplify certain sums of two polygamma functions to
 trigonometric functions), so I think it shouldn't be an obstacle to
 closing this ticket.
