Oh, thanks for mentioning this. I took a closer look at your patch and
realized that it actually would cause -- handling to leave a Greek omega
behind. It may be that we want to move all of that stuff, but if so more
lines have to be removed.
Brendan, here's what I applied upstream (line numbers will be much
different):

I don't think the \*(Tr stuff was doing anything; it looked like a way to
add other transforms later, but the Tr string was never defined.
