clang-format produced code that (choose all that apply): 
- Doesn't match Chromium style
- No sane human would ever choose

Here's the code before formatting:

  if (action == @selector(showGuessPanel:) ||
      action == @selector(toggleGrammarChecking:)) {

Here's the code after formatting:

  if (action == @selector(showGuessPanel:) || action == @selector
                                                  (toggleGrammarChecking:)) {

Here's how it ought to look:

  if (action == @selector(showGuessPanel:) ||
      action == @selector(toggleGrammarChecking:)) {
