"""Fixer for except statements with named exceptions.

The following cases will be converted:

- "except E, T:" where T is a name:

except E as T:

- "except E, T:" where T is not a name, tuple or list:

except E as t:
            T = t

This is done because the target of an "except" clause must be a
    name.

- "except E, T:" where T is a tuple or list literal:

except E as t:
            T = t.args
