Yep, that seems a more sensible definition of core. All core libraries
MUST be available to all Haskell implementations. If/when that
direction is taken, things can be split out, but for the moment this
is a future thing.

I don't want to replace it now, but this might be something for the
future, if the code is examined in detail, and seems to the same

I don't want to evolve or enhance FilePath, I want it to reach a stage
where it provides a useful set of operations, and freeze it. I also
don't want to pick up the responsibility for maintaining the File
related chunks of base :)
