Hallo!
We already have two devel_0_39, separated not by cvs but by #ifdef and makefiles. Now it's getting somewhat cumbersome for me, but it seems that in addition to that, it's getting somewhat cumbersome for the only person (?) who still works on devel_0_39 outside of DesireData. Well, what do you want us to do, I don't think that you really want us to stay in that uncomfortable position forever? :)
No, but you said it yourself: you joined (after impure data) the pd_devel branch so that you can also benefit from those improvements ...
Now there is already the main and devel/desire_data branch and I think such a marginal problem as you have (the beautification ...) should not be the reason for one more branch ...
