Difftastic incorrectly viewing indentation changes as non-syntactic in python

[Joel-Singh]

Line indentation is significant in python, and doesn't show up on difftastic when it changes.

Here's a contrived example consisting of old.py and new.py:

old.py

foo = "outer"

def contrivedFunctionExample():
    foo = "inner"
    print(foo)

contrivedFunctionExample()

new.py

foo = "outer"

def contrivedFunctionExample():
    foo = "inner"
print(foo)

contrivedFunctionExample()

The only difference between them is the indentation of print(foo).

They each print different things:

> python old.py
> inner
> python new.py
> outer
> 

And here is what difft outputs:

> difft old.py new.py
> new.py --- Python
> No syntactic changes.
> 

No syntactic changes despite the files having different output.

Thanks for the report! This is a dupe of #587.
