I tried this patch, and it doesn't seem to help.  That is, if I have a
tag-order style, I get the same behavior as the old _combination: it
completes the user part of the users-hosts from my-accounts, but then
offers all possible hosts as completions for what comes after the @.

Is there something else I should be doing, or was that patch not meant
to solve my problem?
