Hi Willy,

the problem was, I wanted to compare my version to the upstream LZ4 to find bugs (as with my last patch version: wrong indentation in LZ4HC 
in two for loops). But since the LZ4 code is a pain to read, I made additional style cleanups "on the way".
Hope you can manage to review the patch though, because it is difficult to separate the cleanups now.
Please feel free to ask if you stumble upon something.

Greetings,

Sven
