“Copy Profile From Stack Overflow” didn't copy alternate OpenID

Per "Copy Profile From Stack Overflow" didn't copy alternate OpenID, it is by design that all OpenID changes must be done individually for each site account, meaning that less-used accounts may not have a working OpenID even if the user updates the associations for more-used accounts.

Please make this clear in the warning shown when a user tries to copy his/her profile, possibly with the misconception that updating OpenID associations is part of it.
