List and ListStream walked the destination with afero.Walk, which uses
Lstat and so reported a symlinked metadata/ or blobs/ directory as one
file, while Put, Get and Stat follow the link. The store then listed as
empty, and prune removed the local snapshot records and deleted every
blob. Both listings now walk a view of the filesystem without its Lstat
method, so afero falls back to Stat and enters the link.
A symlink loop is not detected: it is followed until the system refuses
the path for too many levels of links, and the listing fails.
