[New-bugs-announce] [issue26095] Update porting HOWTO to special-case Python 2 code, not Python 3

[Brett Cannon]

New submission from Brett Cannon:

As pointed out by http://astrofrog.github.io/blog/2016/01/12/stop-writing-python-4-incompatible-code/, special-casing Python 3 code instead of Python 2 code when writing Python 2/3 code will lead to breakage when Python 3 comes out. There should probably be a note in the porting HOWTO mentioning that you should always special-case Python 2 code and not Python 3 code.
