Can you add also detection of mixed whitespace? E.g. tab followed by space in 
multilinear indentation? Only as warning. Thanks

These checks can generate infuriating false positives when your patch modifies 
upstream code which has trailing or mixed whitespace in either context or 
removal lines; in this case, removing a line with trailing whitespace and 
replacing it with one which doesn't would generate a warning.  Mixed whitespace 
is also part of some coding styles, notably the kernel's.

Cheers,
Daniel

This code checks for the trialing whitespace only in the lines added by the 
patches. The context lines or removed lines are not checked. It is easy to 
check for mixed whitespace also, but before doing that I would like to know the 
final decision about it, as I see some objection to it too.

Thanks,
Nitin
