Merged verses are repeated

I received an And Bible bug report for this issue. I can reproduce it in Bible Desktop and And Bible but not in Xiphos. Therefore I suspect a problem with JSword, or possibly with both BD and AB.

To view an instance of the problem open TurNTB (New Turkish Bible) in Bible Desktop and display Eph 2:4-5. Verses 4 and 5 should be merged but unfortunately verses 4 and 5 are duplicated. Also Heb 2:2-3 has the same problem and many other verses in TurNTB.

I am not familiar with C++ Sword code but it might be good to check how Sword handles merged verses because Xiphos does not have this problem.

A possible fix might be to check if a verse is identical to the previous, and if so ignore it. I can see how I might implement this in AB code but you may like to implement a fix in JSword, however I can't think how that would be done.
