Have at it!

The only real reason for my counter-patch was the state of
that code.  One shouldn't have to puzzle over that few lines
of code to comprehend what it is doing unless it is critical
fast-path.  I'd pretty much refactored the conditional by
the time i was sure what it was doing to even evealuate the
patch.  If i have to do that the code is more difficult to
support that in needs to be.  A refactoring of outer the
loop seemes in order; with a lot more whitespace.
