Comment 2 for bug 1746536

services/item.js defines the service.spawnHoldingsEdit function that explicitly sets `record_id: 0, // disables record summary`

the user/abellenir/lp1746536-edit-volume-from-item-status branch (http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/abellenir/lp1746536-edit-volume-from-item-status) will supply the record_id if (and only if) exactly one record is selected.

selecting several copies that all belong to the same record seem to work ok, but i wasn't sure how to best handle having multiple record_ids to choose from, so kept the behavior unchanged.
