Wasn't this about not having robot messages in regular PRs (even if the second link make no sense related to that issue)?

The first link made no sense to me, but should point to

awesome-www/.travis.yml

Line 96 in 8156f0d

git commit -m "Update from Travis for awesome-www@${commit_hash}"

probably.
