The current repairer just uses the normal upload code, so if a server is serving a corrupted share but it doesn't realize that its share is corrupted, then when the uploader contacts the server to offer to upload shares, the server will say 'Yep! Already got a share of that file!' and the uploader will believe him and not bother to upload that share anywhere else. Therefore, the current repairer doesn't repair corrupted shares, only missing ones.

Major because it could cause data loss.

Since we're revisiting how repair works in 1.11, I think that in that version, --repair should imply --verify for tahoe deep-check.
