remove /*=NULL*/ comments

Command used:
    sed -r -i 's|/\*=NULL\*/||g' "$file"
We have to collect all these issues regarding indentation. Then, we should have a discussion and fine tune it. The rule now tries to save vertical space. It it can group two parameters next to each other then it will do it. That's possible now because /*=NULL*/ was deleted. But once we're done with the cleanup this heavy changes in indentation will also stop.
