> Snapshots of a snapshottable directory are allowed to have arbitrary names.
> Presently, if you create a snapshot with a snapshot name that begins with a
> "/" character, this will be allowed, but later attempts to access this
> snapshot will fail because of the way the {{Path}} class deals with
> consecutive "/" characters. I suggest we disallow "/" from appearing in
> snapshot names.
> An example of this is in the first comment on this JIRA.
