Pass copied file list on success

It would be extremely useful if the list of files copy()d were passed to the callback/then. Even more so when a filter is used.

fs.copy('/tmp/myfile', '/tmp/mynewfile')
.then(files => {
  console.log('success!', files.join(', '))
})

As a short-term solution, why not just log in filter()? I’m not convinced adding options for this is a good idea. Long-term, I think we need to move to streams or AsyncIterators on these operations.

Closing as future for the time being.
