Thanks for this.

Just for my own notes, the possible approaches to this right now are
keeping full copies of the previously-edited record in the record's
cache, and allowing the user to cycle through which record is "current",
and/or keeping track of specific field edits via something that looks
like vCard's synchronization mechanism:
