Fail restore for a requested path that matches nothing (closes #309)

snapshot restore said nothing about a requested path that matched no
entry in the snapshot (a typo, a relative path, or a path through a
configured snapshot path that is a symlink, whose entries are stored
under the resolved directory) and exited 0, also when nothing matched
at all. Each such path is now named in a warning, and restore returns
an error after restoring the paths that do match.

Making a path through a symlink match is not part of this change.
Judgement call: when files also fail to restore, that error is the one
returned; the unmatched paths are still named.
