RFR: CODETOOLS-7901397 - Flag -b is ignored in webrev

[Jesper Wilhelmsson]

Hi,

Please review this fix to make webrev care about the -b flag and make it 
possible to produce diffs with whitespace changes.

Bug: https://bugs.openjdk.java.net/browse/CODETOOLS-7901397
Webrev: http://cr.openjdk.java.net/~jwilhelm/CT-7901397/webrev.00/

I will also need a sponsor to push this change.

Thanks,
/Jesper
