Thank you for doing this investigation and fix. This is a big deal. I want to take the proper time to fully understand the explanation that you gave here before merging, and I will try to do that before the end of the day. |

I'd like to see if I can add a test case to cover this too, since it's such a tricky case. |

As andrew said, this needs a test. |

Fixes #54
To sum it up, when you try to download a remote directory called
remote-dirfrom a bucket, and specify the local directory aslocal-dir, I would expect just the contents ofremote-dirto download, not the directory itself, soremote-dir/shouldn't need to be pushed toallS3Objectswhen listing remote objects, but it is right now.If
local-dirhas a subdirectory calledfoo(valid directory that also exists remotely and thus should be retained), it will get deleted on the next download attempt. Because of the extraremote-dir/entry inallS3Objects, when you start diff'ing the remote objects against the local ones, you end up checking if the stringfoo/is contained within theremote-dir/s3Object.key string, which is an empty string after the prefix truncation. And since it isn't,deleteLocalDir()gets called.
