I think what would help a lot is if there were added,
to the conversion
script, something that made [[Poker/Bluff]] (for instance) into
[[Poker/Bluff|Bluff]]. It appears that what the script does right now is
to convert instances of [[/Bar]] on a [[Foo]] subpage into [[Foo/Bar]].
I'd say it would be better in 95% of the cases to convert it instead into
[[Foo/Bar|Bar]].
I fixed the conversion script so it does that now, although it might become
confusing for the reader if (in your example) there's a "real" [[Bar]]
article too, because it would look exactly like [[Foo/Bar|Bar]]. Well, I
guess we can't have the cake and eat it...
