 Ok

 > - I'm -1 on using `show(P)` in the doctests; IMO it is better to return
 the plot as it actually gets doctested in a fashion.

 Ok, I also had my doubts.

 > +            sage: PD = HyperbolicPlane().PD()

 >   }}}
 >   I think the random test is somewhat better. However, I think you
 should add an additional test with this specific geodesic and give the
 commands for the user to reproduce your picture.

 Agreed. I changed the random_geodesic to make consistent and good-looking
 into the doc. I think you are right, we better move the random_geodesic to
 the test directive.

 > - Can you explain this change:
 >   {{{#!diff
 > -            sage: h = PD.get_geodesic(4/5*I + 3/5, 9/13*I + 6/13)
 > +            sage: h = PD.get_geodesic(4/5*I + 3/5, I)
 >   }}}

 Well, better looking picture I guess.

 > - Replace {{{:math:`x^2+y^2-z^2=-1`}}} with {{{`x^2 + y^2 - z^2 =
 -1`}}}.

 Ok

 > - I don't understand the point of the comments in the `.. PLOT::`
 directives. Moreover, the numbering either has no meaning or it will loose
 meaning as soon as someone adds another plot.

 oops, it was debugging code, I'll remove it.
