Fix handling of series with the [PATCHvX] defect

b4 tries to handle subject lines such as "[PATCHvX]" by replacing
the subject line in situ, but seems to do a rather bad job of it,
resulting in only the first patch of the series being picked up.
Fetching <20201026134931.28246-1-mark.rutland@arm.com> does exhibit
the problem.

Fixing the re.sub() expression allows normal funtionalities to be
restored, and the above series to be fetched.
