Thanks, I think most of these make sense. I'm not too sure what to do 
about the parts you marked with "TODO" though; it'll take some thought 
for each of them. (For example, I feel like there's a better way to let 
users customize the keys in em-rebind.el and elsewhere.)

How about removing them from the patch, and then we can merge the remainder?
