The indentation of continuation lines in this driver is a bit inconsistent, but the above change matches the next conditional and the rest of the function (which does not use open-parenthesis alignment). > Maybe your preference is double indentation for continuation lines rather than > aligning them roughly with the opening parenthesis of the calling function?
