Thank you for opening a PR Barry! But there is some disputation. Barry 
and Victor prefer moving a brace on a new line in all multiline 
conditional cases. I think that it should be done only when the 
condition continuation lines and the following block of the code have 
the same indentation (as in the example above), and the following code 
is enough readable:

         if (PyErr_WarnFormat(PyExc_DeprecationWarning, 1,
                              "invalid escape sequence '\\%c'",
                              *first_invalid_escape) < 0) {
             Py_DECREF(result);
             return NULL;
         }

What other core developers think about this?
