82cd1efd6015 Talking about clean and well formatted code all the time and never run mine through a beautifier while still having a mix of tabs an spaces. So now Uncrustify has cleaned my code. Still two unsatisfying points are left. indenthandler.cpp line 467 a space between case label and colon has been removed and like on line 503 some code lines got indented without setting that explicitly.
