"""Fixer that changes filter(F, X) into list(filter(F, X)).

We avoid the transformation if the filter() call is directly contained
in iter(<>), list(<>), tuple(<>), sorted(<>), ...join(<>), or
for V in <>:.

NOTE: This is still not correct if the original code was depending on
filter(F, X) to return a string if X is a string and a tuple if X is a
tuple.  That would require type inference, which we don't do.  Let
Python 2.6 figure it out.
