Summary: tokenize module does not detect inconsistent dedents

Initial Comment:
The attached code snippet 'testcase.py' should produce an 
IndentationError, but does not.  The code in tokenize.py is too 
trusting, and needs to add a check against bad indentation as it 
yields DEDENT tokens.

I'm including a diff to tokenize.py that should at least raise an 
exception on bad indentation like this.

Just in case, I'm including testcase.py here too:
------
import tokenize
from StringIO import StringIO
sampleBadText = """
def foo():
    bar
  baz
"""
print list(tokenize.generate_tokens(
    StringIO(sampleBadText).readline))
