c!! adds newlines

[gfixler]

If I have this:

(* (+ 1 2) (+ 3 4))

And I'm in the (+ 3 4) form, and this is on line 5, and I do c!!, I get:

(* (+ 1 2)

7)

I seems to be adding n newlines before the result, where n is the line I'm currently on. Thus, it works perfectly on the first line of the buffer, and linearly worse as I move down the lines.

I've done a verb map ! and come up empty.

Artifact of me newline padding the source to produce the correct stacktrace. Fixed but might have introduced an edge case or 2.
