docs: A safer version of Xapian.enquire.get_mset
  
          Simply wraps the Xapian version and catches any `Xapian.DatabaseModifiedError`,
          attempting a `database.reopen` as needed.
  
          Required arguments:
              `database` -- The database to be read
              `enquire` -- An instance of an Xapian.enquire object
              `start_offset` -- The start offset to pass to `enquire.get_mset`
              `end_offset` -- The end offset to pass to `enquire.get_mset`
