'mode' docs fix: the file must always be opened in binary in Python3. Bug in Wave_write.close: when the close method calls the check that the header exists and it raises an error, the _file attribute never gets set to None, so the next close tries to close the file again and we get an ignored traceback in the __del__ method. The fix is to set _file to None in a finally clause. This represents a behavior change...in theory a program could be checking for the error on close and then doing a recovery action on the still open file and closing it again. But this change will only go into 3.4, so I think that behavior change is acceptable given that it would be pretty weird and unlikely logic to begin with.
