<p>
<div>
<pre>The C++ keyword `class` in an ObjC selector name causes subsequent code to be
mis-formatted.
Minimal repro:
% cat /tmp/foo.m
- (void)class:(id)clazz { }
// This should not be indented.
- (void)foo { }
% ./bin/clang-format -style google -debug /tmp/foo.m
Args: ./bin/clang-format -style google -debug /tmp/foo.m
File encoding: UTF8
Language: Objective-C
