Okay, no point in adding complexity in notmuch then.

Testability is a good point; otherwise we'd have to add an extra tool
for testing the interface, which is also silly. If we don't add restore
support now, I think we can consider this a documentation issue.

One more thing: do we need to ensure we don't emit gzipped stuff to the
terminal?
