Why remove this function?

I don't really like the assumption that package names don't have slash
in them (this is false for CEDET, for example, and I think that AUCTeX
also uses names with slash for its style files).
But I guess it's OK for now.

We follow the convention to only use "path" to mean a list of
directories such as $PATH, load-path, and things like that.
I.e. "/foo/bar/baz" is a *file* name, not a "path".
