As a datapoint, it sounded to me more like Gustavo saying, "I'm pretty
sure I know what I'm doing here, but this is hairy code and I'd like to
keep the old code around for a bit as a cross-check in case it turns out
I'm wrong."  But if Gustavo's code already passes the regex regression
suite, I would say it's just him being suspenders-and-belt -- which in my
book as a tech support-type person is a Good Thing.
