[plt-scheme] xxx chooses MzScheme as preferred language

Greetings!

I tried originally to use plain regexp, but there were a number of desired
features that influenced the switch over to pregexp. Unfortunately, there
did not appear to be any documentation that jumped out at me while doing
the work to say that one library had a performance advantage, and I hadn't
gotten far enough with the original implementation to compare.

Regards!
