The main point of missing clarity there is that we still need to settle on
whether blank lines should also be between blocks where the earlier falls
through to the latter. Iirc you'd like to have blank lines in such cases
nevertheless, while I'd prefer to make the falling-through visually easy
to recognize by not putting blanks lines between the "fallthrough;" /
fall-through comment and the successive "case ...":.
