The first comments in vectors/sets/structs don't get indented properly

[evantypanski]

Given some ports definition (like is in the Spicy protocol plugin template), the indentation doesn't start until the first item, so comments get unindented:

const ports = {
-	# This comment gets unindented
+# This comment gets unindented
	1234/tcp,
	# This one stays, though
	5678/tcp,
};

I would expect no change.
