check-webkit-style spits error: `ERROR: Source/WebCore/CMakeLists.txt:30: There should be exactly one empty line instead of 0 between "inspector" and "loader/appcache". ` on a patch that adds a couple of lines to WebCore_INCLUDE_DIRECTORIES. However the patch has nothing to do with the error mentioned. The occurrence of "inspector" and "loader/appcache" happens at lines 545 and 547 (not 30), and there is an empty line between them. See bug 133316 for details.
