The original motivation was that:

uncurry (++) . splitFileName === id

And hence dropFileName = fst . splitFileName

However, in practice I think its more useful to use takeDirectory,
since usually the trailing slash gets in the way.

Those were the original reasons, but it is possible they were bad
reasons from the beginning.
