param tweak to get copies to flesh on lineitem details, and yes, open-ils.cat will handle volume and bib deletion, as well as hold retargeting.  But we still need to cancel holds in the case where the bib gets deleted.  If the bib isn't deleted (because other copies were added outside of acq), holds that came from acq may or may not target those non-acq copies.  If they don't and any holds become unfulfillable (say due to hold permit policies), we'll just let them lay for now rather than try to figure that out.

From my open-ils.acq.lineitem.cancel branch
