--------------------+---------------------------------
 I would like to solve the pep8 vs. flake8 version conflict and ticket
 #50513 for good. Therefore I propose to

  * update py-pep8 to 1.7.0
  * at this point: remove py26, py33 and add py35 subport
  * this requires that py-autopep8 has the same subport retired/added
  * being there: upgrade as well

 The port is openmaintainer. I therefore could proceed myself if there are
 not relevant concerns.
