[issue11319] Command line option -t (and -tt) does not work for a particular case

[Jérôme Radix]

New submission from Jérôme Radix <jerome.radix at gmail.com>:

The attached example mixes tabs and spaces but python does not report any warning when used with -t.

Line 4 contains 1 tab. Lines after line 4 contains spaces.

Tested using :
Python 2.7.1 (r271:86832, Nov 27 2010, 17:19:03) [MSC v.1500 64 bit (AMD64)] on win32

C:\>python -t test_tt.py
