Grow right grows over curly braces

[nickik]

While developing I oven had strange non matching endings of functions. I investigated and found the following problem.

{:data (+ 1) 2}

You want to get this
{:data (+ 1 2)}

But when you grow (+ 1) to the right you get:

{:data (+ 1 2})

I will try to fix this myself but maybe somebody is faster then me.

The issue is related to line starts and ends, as it only occurs if the outer brackets are on the line start or end.
It occurs for both grow left and grow right
