---------------------+------------------------------------
 In `rend_encode_v2_descriptors`, an extra newline is added at the end of
 the descriptor. However, rend-spec.txt doesn't specify this extra newline.

 atagar mentionned on IRC that it would be surprising if that is the
 intended behaviour since other type of descriptors don't have it:

 {{{
 < atagar> It's the only descriptor type with it, so I'd be surprised if it
 was intended. ;)
 }}}

 Thus this should be fixed in the tor code and not in the spec.
