Automatically taking care of directories?

[Pomax]

If you're packing up entire directories based on flat lists of files (e.g. find . output) having to figure out when and whether to call archiver.directory is rather painful. It would be much nicer if append calls like:

archive.append('string cheese!', { name: 'some/nested/dir/file.txt' });

automatically did the right thing. It is unclear from the README.md whether it does that right now, but if it doesn't, could that be added?
