While reviewing some dts diffs recently I noticed that the hunk header logic was failing to find the containing node. This is because the regex doesn't consider properties that may span multiple lines, i.e. property = <something>, <something_else>; and it got hung up on comments inside nodes that look like the root node because they start with '/*'. Add tests for these cases and update the regex to find them. Maybe detecting the root node is too complicated but forcing it to be a backslash with any amount of whitespace up to an open bracket seemed OK. I tried to detect that a comment is in-between the two parts but I wasn't happy so I just dropped it.
