You're right that a conventional "if" block is not only more readable,
but also faster and more efficient code.  Sorry you have to deal with
code written like that!  That'd frustrate any sane programmer.  It might
bother me enough to write code to reformat the program to convert that
style to something sane!  There are times when the ternary (did I get
that right?) operator is useful and clear.
