Subject: [PATCH] Use raw strings for each part a regex

The backslashes in this regex are causing `DeprecationWarning`s to
appear because they aren't valid escape sequences. Clearly they're meant
as literal backslashes given the context, so using raw strings makes
sense. I set the other parts of the regex as raw strings as well since
escape characters are far less common in regular expressions than
backslash characters, and it's easy to forget to make the string raw
when modifying an existing one to contain a new backslash.
