Since the only caller, verify_absent, relies on the fact that o->pos

its position.
I suspect that the original reasoning of this behaviour might have been in
anticipation of other callers, but I agree with your reasoning especially
because I do not think of a good reason to want to receive the number of
entries to skip as the return value and not have o->pos pointing at the
right place.
Thanks, queued.
