Will add "coextend=: coinsert" in colib solve the backward compatibility problem?
On another unrelated note. The removal of "coextend" broke some of my scripts. The fix was simple (edit and replace coextend with coinsert). I vaguely remember this being discussed in the forum and a quick gmail search of all my forum messages warned us that "coextend" would be removed.
