The regexp doesn't match the example. It does match
fixes: bug#123(, bug#345)))))))))))))))))
which is probably not what you intended :-)
In Perl regular expressions, alphanumeric characters always match
literally unless preceded by a backslash, and non-alphanumeric characters
always match literally if preceded by a backslash.
So, take out the backslashes before the parentheses, and you are fine.
OTOH, every () sets one of the $1 $2 ... variables; if you want to avoid
that (that's more for the actual implementation than for the policy
manual), use (?: ) instead of ( ) to not touch those variables.
Here's a short explanation of the corrected regex:
fixes: matches "fixes:"
\s* matches zero or more whitespace characters
(in C: one of " \t\n\r\f")
bug matches "bug"
(thing)? matches "" or "thing"
\# matches "#"
\d+ matches some digits, at least one
, matches ","
(thing)* matches "", "thing", "thingthing", and so on
/thing/i matches "thing", "Thing", "tHiNg", and so on
