[sheepdog] [PATCH stable-0.6 0/4] stable-0.6 update

[Hitoshi Mitake]

This update contains small fixes for bugs which can be found in
ordinal settings.

If anyone disagree about this backporting and the opinion is accepted,
I'll revert the patches from stable-0.6.

Feel free to comment on this selection, thanks.
