Given the source of 'file' in this case, this is probably not
significant, but there's a possible gotcha here if empty strings are a
possibility.

>>> empty = ''
>>> empty[-1]
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
IndexError: string index out of range
>>> empty[-1:]
''
