Okay.

However, I'd like to NAK some bits of c5b60b5e67af8be4c58d3ffcc36894f69c4fbdc1
now that I see it...

Will a patch -R of below be correct enough for you?  Otherwise, please
send me a new patch.

(This is one of the reasons why I'm not so keen on whitespace fixes, also
having to resolve merge conflicts, peturbing the history of the code etc.)

_Please_ don't do either of these.  The whole point is to line stuff up so
that as the eye scans down the lines, it can easily pick out the differences
in stuff that's otherwise greatly repetitive.

I never would of thought this. So the != has to be lined
up so things don't break?!
