py3: silence the final IOError by closing stdout/err slightly early

Fixes the following test failure:

  $ hg status >/dev/full
  abort: No space left on device
  Exception ignored in: <_io.TextIOWrapper name='<stdout>' mode='w' ...
  OSError: [Errno 28] No space left on device
  [120]

        # There's not much we can do about an I/O error here. So (possibly)
        # change the status code and move on.
        except IOError:
            status = -1
    sys.exit(status & 255)

def _getsimilar(symbols, value):
    sim = lambda x: difflib.SequenceMatcher(None, value, x).ratio()
    # The cutoff for similarity here is pretty arbitrary. It should
    # probably be investigated and tweaked.
