I'd say it would be better in 95% of the cases to convert [[/Bar]] on page [[Foo]] 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...
But that's exactly the case now with [[Foo|Bar]] of any kind. That's a feature, not a bug.
Of course, I'm going to go through all of those pages manually and change every [[Poker/Raise|Raise]] into [[Raise (Poker)|raise]] anyway, so it doesn't much matter to me. 0
