s�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
