Indeed, it looks like portions of ediff expect symbols like file-A and
file-B to be dynamically bound, but also passes them through as
arguments to functions. I'm not sure what the best way to deal with this
is, since if we just mark them as special the lexical binding will
shadow the global binding anyway.

In the meantime, feel free to revert that patch if its causing issues.
