Merge 9acf9ddc75 into 9f6a1f7e79

* .go files are now tagged with diff=go for better diffs
* go.sum is tagged with generated which suppresses the diff
* go.sum is tagged with merge=ours to reduce merge conflicts

go.mod isn't tagged with generated since it's useful to see it on
dependency bump PRs.
