I don't want to introduce error-prone options.  I think it would make 
sense for tla fall back to full inventories in some cases for selected 
commits.

To support deletes, tla should automatically fall back to a full 
inventory if an ID disappears.  The purpose of the inventory is to 
distinguish deletes from moves.

Legal adds create a previously-unused ID, so they don't need special 
support.

If an apparent add contains a duplicate ID, it may be a move.  If 
out-of-selection-moves aren't supported, you can error out.

If out-of-selection moves are permitted, or you want to give a clearer 
error, you need to  fall back to a full inventory to distinguish the two.
