I do match for the parent, but it doesn't seem to help.
Here's what tree-sitter explorer shows for the following:
require (

)

(require_directive require ( \n ) \n)

If I put point on the line right below r and do C-S-a, tree-sitter explorer 
shows:
(require_directive require (*\n ) \n)
The * indicates that part is highlighted.

The second I make it "proper" like so:
require (
test v1
)

I can hit TAB and it will indent properly (but not anything above it, only that 
line and anything below).

I would think that checking parent-is for require_directive would be enough but 
it's not somehow???
It's instead matching my no-node rule...

(Also I attached a new patch which contains a few more indent rules for go.mod 
I forgot about).
