I know that I could rewrite the method like this:

if size == None:
line = self.file.readline()
else:
line = self.file.readline(size)

...but this seems to me exceptionally awkward. (Actually, it's worse
than awkward: it fails to complain when the overriding method is
called with the argument None.
You could of course do:
def readline(self, *args):
line = self.file.readline(*args)
# etc., etc.
But this has its drawbacks.
Like what? (I'm pretty new to Python and these drawbacks are not
obvious to me.)
One thing I can think of: The help system (and the code autocompleter
found in some editors, and other introspection tools) can't tell you the
name/number/default value of the arguments anymore: they're all masked
into a generic *args
