[Python-Dev] self._backupfilename in fileinput

[Skip Montanaro]

Working my way through the unqualified except: clauses, I found one in
fileinput.py that looks very straightforward:

    try: os.unlink(backupfilename)
    except: pass

To make sure that OSError was all that could be raised I started looking at
what values backupfilename could assume.  Then I started looking at
self._backupfilename.  This weird beast takes on values of three distinct
types: None, 0, and various strings.  

While it's not technically broken, is this something worth fixing?  My
inclination is to just add OSError to the except clause and let someone else
worry about fixing something that's ugly but not really broken.
