Save original names that don't work as filenames (e.g., `.` and `..`). We restore these names as appropriate---if a file is `rename`d with the _same_ name, we leave it alone. But renames to fresh names destroy original names. Resolves #29. There is no way to create a file with such a name: the metadata is purely copied. There's a TODO note in the code to allow users to inspect and edit this metadata, but it's not worth exposing until somebody asks for it. (I mean, really, please don't use `.` or `:/` as a property name.)
