if git show -s --format=%s $1 | grep -qE '(DO NOT MERGE)|(RESTRICT AUTOMERGE)'; then

DO NOT MERGE and RESTRICT AUTOMERGE very often lead to unintended results
and are not allowed to be used in this project.
Please use the Merged-In tag to be more explicit about where this change
should merge to. Google-internal documentation exists at go/merged-in

If this check is mis-triggering or you know Merged-In is incorrect in this
situation you can bypass this check with \`repo upload --no-verify\`.
