Fine.

The Obsoletes: in pidgin-evo causes pidgin-evo to be pulled in, which is 
fine. The package should obsolete pidgin packages prior to the split but 
not the ones after the split.

Not needed if pidgin-evo depends on pidgin itself - the regular 
dependency mechanism should pull the main pidgin package in. And since 
the new pidgin package is versioned later than the split, it's no longer 
obsoleted by the pidgin-evo subpackage. Does that not work?
