CRM-6994 Search Builder "IN" operator does not allow space in Membership Type names

In 3.2.3 Search Builder expects a name not an ID number for Membership Type searches. If you use the "IN" operator the form returns an error if there is a space in the Membership Type name, ie searching for "IN ('Major Donor','Student')" does not validate. Adding a space to the preg_match fixes the problem. Simple patch below.
