adjust the clang-format penalties to reduce string breaking

this corrects some style glitches such as:
```
        long_function_call(arg, arg2, arg3, arg4, arg5, "str"
                                                        "ing");
```
...by adjusting the penalties for breaking strings and call
parameter lists.
