Extended Description

clang-format binds method argument : tighter than @​selector(, resulting in the following odd formatting.

input.m:

- (void)test {
    if ([object respondsToSelector:@selector(selectorNameThatIsReallyLong:param1:param2:)])
        return;
}

$ clang-format -style=llvm input.m

- (void)test {
  if ([object respondsToSelector:@selector
              (selectorNameThatIsReallyLong:param1:param2:)])
    return;
}

$ clang-format --version
clang-format version 7.0.0 (tags/google/stable/2018-01-11)

The @selector and its ( should remain together

I have not been able to find a combination of config options that avoids this behavior.
