Can't mirror flat repositories

[frntn]

I'm unable to fetch flat repositories

Flat repo is like :

deb uri directory/

In aptly this must be translated like this :

aptly mirror create issue905 uri/directory ./
aptly mirror update issue905

So the package should be downloaded using this path

uri/directory/*.deb

But the directory appears twice in the download path

uri/directory/directory/*.deb

Hence we receive a 404 and are unable to update the mirror

Detailed Description

$ gpg --no-default-keyring --keyring trustedkeys.gpg --keyserver keys.gnupg.net --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9

Issue #47 reported the same behavior, and I still have the same issue so I believe this is a regression :

$ gpg --no-default-keyring --keyring trustedkeys.gpg --keyserver keys.gnupg.net --recv-keys 9B7D32F2D50582E6

See my reply to the latest question on that topic. Looks like it now only works if you use the last part (directory) of the URL as the distribution name.
