We should fix the code for 3.2 through 3.4, but change the docs for 3.2 and 3.3 to remove the parenthetical note.  For 3.4 we can leave the parenthetical note but say this is new in 3.4 (or maybe, that it doesn't actually work in some versions < 3.4).  I agree that for code to work consistently across all Python 3.2 and 3.3 microversions, extension code is going to have to include both flags anyway.
