routing: Fix breakages with routing on some versions of Python.
Finally figured what happened with change 6baa94da8b16 (this is a Mercurial
hash by the way if you're looking at the Git mirror). Between Python 3.6 and
3.7 there was a change where the percent sign ('%') went from being escaped by
`re.escape` to _not_ being escaped. So now we need to use different regex
patterns dependin on the Python version, yay.
