Package textdiff renders plain line diffs of small, human-reviewed texts
such as golden files. It is shared by the test harness (want.yaml
mismatches) and the static check core (XRD golden drift).
Lines renders a plain line diff between two texts: unchanged lines are
prefixed with two spaces, removals with "- ", additions with "+ ". Golden
files are small and reviewed by humans, so a full LCS diff with complete
context reads better than a windowed unified diff.
