Issue 5704: Command line option '-3' should imply '-t' (original) (raw)

The '-3' command line option in Python 2.6 is supposed to warn whenever encountering something that would throw an error in Python 3. Mixing of tabs and spaces has become illegal in Python 3. However, Python 2.6, called with '-3', passes silently over this unless '-t' was given, too.

Would it not be more consistent to let '-3' imply '-t'?
