Hi Denton

You say they are almost interchangeable and then use them as if they are 
completely interchangeable. I think they are interchangeable, the only 
difference I could see is that the code in rebase.c redirects stdin when 
forking 'git stash apply' but the sequencer does not, I don't think this 
matters.

Best Wishes
