Thanks!

@borkdude I found that this change breaks formatting for nested maps. For example, if you have a map:

{:a {:b 1}}

and do:

(r/assoc-in m [:a :c] 2)

Previously, the resulting map would be:

{:a {:b 1
     :c 2}}

And now:

{:a {:b 1
 :c 2}}

The problem is that z/position returns the position relative to the inner map instead of the outer map. Do you know whether this is expected or it is a bug in rewrite-clj? If you see fit, feel free to revert the PR while we figure this out.

I reverted for now. We can revisit another time.
