Prefix non-name path components

Browse Source 
To address the possibility of confusing registry name components with
repository paths, path components that abut user provided repository names are
escaped with a prefixed underscore. This works because repository name
components are no allowed to start with underscores. The requirements on
backend driver path names have been relaxed greatly to support this use case.
