Add a simplistic tool to clean up whitespace This hasn't been tested enought, but it seems to get really close. It assumes that clang-format is in your patch. Run perl scripys/whitespace.pl FILENAME and you'll get a diff of what it things is wrong with that file. If you like what you see, simply pipe the output into patch -p0 Signed-off-by: Dirk Hohndel <dirk@hohndel.org> 2014-02-13 06:30:03 +00:00			`#! /usr/bin/perl`

Fine tuning of the whitespace / coding style post processing The struct / class regex was way too relaxed. Having the parent class on the same line usually looks better. clang-format appears to do something odd with continuation strings - even with UseTab: Always it indents those with four spaces.
