'edt-b.st' adds a bit of crutch to the translator. In desperation I
simplified the transformation for && and || dramatically. The new
transformation requires only a single variable for any condition
expression, and can be implemented with a cute recursive algorithm.

PS. The transformation for the curious:
if (A) X;
becomes:
{ Bool flag;
flag = A;
if (flag) X;
}
-----
flag = A && B;
becomes:
flag = A;
if (flag) {
flag = B;
}
-----
flag = A || B;
becomes:
flag = A;
if (!flag) {
flag = B;
}
-----
flag = !A;
becomes:
flag = A;
flag = !flag;
