String constants in Python are weird - raw strings doubly so.
In a raw string, backslashes are not special - unless followed by
a quote character, when they simultaneously escape the quote and
also insert a literal backslash.

I presume there was originally some reason for this bizarre behaviour
- it'd be interesting to know what it is/was, if anyone knows?
