[Bf-committers] Joining objects and merging UV Layouts has Changed in Behaviour (2.69)

[Bastien Montagne]

Why not simply add a toggle to join cd layers either by name or by 
indices (with first option by default)? I think it can be useful. And we 
also use CustomData_merge in other contexts than join op, where we do 
not need name comparison. So as the change is pretty simple (will have a 
patch very soon)…
