*evil grin*

Anyway, I agree that this patch is not worth spending much time on.  I
still think the result is cleaner (perhaps due to my strbuf_addf
allergy), though it's longer and perhaps adding a twelfth variable makes
the function too complicated.  The magic chomping variant is a clever
compromise -- but needs a comment to explain itself.  So if you are
indifferent please just drop it.

Thanks,
René
