'stash' is a logical way to move working-directory changes across branches without having to either (a) really commit, or (b) update to the common ancestor, then up to the target head.

The reason I suggested this is that this would minimize the risks of 
conflicts during unstash. A simple case where the ordering by appearance 
would (possibly) lead to conflict:
- work on head A
- stash
- work on head B, (hack, hack)
- stash
- update to head A
- unstash
This is a typical use case of stash (namely interrupted workflow for 
urgent fix). And having to explicitly name the stash to pop in such case 
seems awkward to me, whereas poping based on ancestor would just work.
