Could or should these printf()'s be advise() calls instead? That would make it easier for users to turn them off if they don't want the extra output. At the very least, we should make sure that they are sent to stderr to discourage scripting around them.
Ah, I didn't know about advise(); looks like it could be reasonable to use here. If nobody objects, I'll change to advise() when the rest of the feedback has come in and v3 is sent.
Thanks!
