Use a raw string for a regular expression

Previously, the string had an unrecognized escape sequence ('\*').
With a non-raw string we could have doubled the backslash, but it's
much cleaner to just use a raw string instead, (so that backslashes
are used for regular-expression escaping, and not also for string
escaping).
