      # This is a suplemental patch that fixes a small bug in the above patch.
      # It's not in trunk yet, but it has been submitted upstream, okayed, and
      # hopefully a version of it will be committed by the time 7.6 comes out.
      # If you're updating this formula for 7.6, email davidbalbert@gmail.com,
      # and I'll let you know if the change has made it into the release.
