I suppose we could use a more complex check in Git's case: if the diff 
is non-empty, check that it doesn't intersect with the diff we want to 
apply, or where it does, the contents are exactly the same. It's more 
complex than the existing one-liner, though.

The commit-and-amend thick is the first that came to my mind too, but 
the above would be more flexible, I guess.

And as for dropping the "registering" step in Git, I suppose that might 
speed up the overall workflow for some people (myself included, 
probably), but it still wouldn't allow you to check in new files 
together with a partial diff in existing one. I think.
