Right, when you have '_' after a '%' you need to make sure the '%'
advances full characters. In my suggestion the test if '_' (or '\') come
after the '%' is done once and it select which of the two loops to use,
the one that do byte stepping or the one with NextChar.
It's difficult to know for sure that we have thought about all the corner
cases. I hope the gain is worth the effort.. :-)
