That's way helpful -- it seemed like it *should* work that way, but  
it doesn't (i.e. the other escape chars are always active -- why not  

I do have an idea for cleaning up all that prefilter code, so I'll  
see if I can fix that all together once I get the tests up and running.

Will hopefully have a decent set of tests to submit soonish (which  
will fail for this behavior ;-).
