Edits containing root map replacement

[arichiardi]

Hi there, I am trying to get all the keys (recursively) that have changed by parsing the get-edits vector and it all works - plus it reads nice.

However, there is an exception: get-edits returns

[[] :r {:foo :bar}]

when the first in the diff is empty and the second populated (in my case {:foo :bar}.

Now, I can special case on that [] but I wonder if I am missing more of the way editscript returns its edits.

The I have two side question 😄

Did I understand things correctly above?

Should we mention this special case in the README, right after:

The first element of an edit is the path, similar to the path vector in
the function call update-in. It might be confusing/unexpected to others.

What's the data that produces this diff? Please provide more context. Thanks.
