I think in this case that would not be appropriate.  It is the
difference between:

	case 1:
	case 2:
	case 3:
		puts("one to three");
		break;

and

	case 1:
		puts("one");
		/* fall through */
	case 2:
	case 3:
		puts("one to three");
		break;

I admit, I am surprised to see multiple suggestions for improvements
to details of the patch.  I guess I should say, except for the log
message, it is

i.e., I don’t see any low-hanging fruit for improving it without
actually taking a deeper look at the surrounding code.  Ralf, can we
have your sign-off?  That way maybe it could be applied and people
could suggest patches on top.

Still, thanks for looking it over.

Jonathan
