Maybe the interactive behavior could look as follows:

- when copying/renaming to "/foo/dir", first do it as we do now.
- if it signals an error because "/foo/dir" already exists, check if
  it's a directory.
- if it's a directory, ask the user to confirm that he meant "/foo/dir/"

That would let the user learn that he should have written "/foo/dir/" in
the first place, and so should slowly get him to avoid the prompt.
