To the proposition given by Steve, I would add "Correct all double
redirects", to prevent not wanted pages to be re-redirected
automatically.
Like this :
* Poker/Hands (linked 1 time - [[correct]])
* Ace-to-six low (linked 3 times - [[correct]])
* Deuce-to-seven low (linked 7 times - [[correct]])
[[Correct double redirects for
these pages]]
That actually sounds like the best solution so far. Maybe with a
checkbox for each redirect, like on [[Special:Undelete]] or
[[Special:Watchlist/edit]]?
