The am-backend drops information and thus limits what we can do:
* lack of full tree information from the original commits means we
cannot do directory rename detection and warn users that they might
want to move some of their new files that they placed in old
directories to prevent their becoming orphaned.[1]
* reduction in context from only having a few lines beyond those
changed means that when context lines are non-unique we can apply
patches incorrectly.[2]
* lack of access to original commits means that conflict marker
annotation has less information available.
* the am backend has safety problems with an ill-timed interrupt.
Also, the merge/interactive backend have far more abilities, appear to
currently have a slight performance advantage[3] and have room for more
optimizations than the am backend[4] (and work is underway to take
advantage of some of those possibilities).
