We loop over the arguments, but every branch of the loop
hits either a "continue" or a "break". Surely we can make
this simpler.
The final conditional is:
if (arg is a rev) {
... handle rev ...
continue;
}
break;
We can rewrite this as:
if (arg is not a rev)
break;
... handle rev ...
That makes the flow a little bit simpler, and will make
things much easier to follow when we add more logic in
future patches.
