When does git include the repository URL in merge commit messages?

Question

it came to my attention that the merge commit messages of my team members look differently depending on who is doing the commit.

Does anyone know: When does git suggest merge commit messages of the first form (i.e. stating the repo url explicitely), and when does it use the second form?

2017-07-05 11:34 Employee 1            M─│─┐ Merge branch 'wip-feature-1' of ssh://repo.company.com:1850/ttt/software into mainbranch
2017-07-05 10:45 Employee 2              │ │ M─┐ Merge branch 'wip-feature-2' into mainbranch

Thanks!

I think they’re using git pull to do their merges. I can also get this with git merge FETCH_HEAD after fetching (which makes sense, since git-pull is documented to be the same as git merge FETCH_HEAD).

git merge with any argument other than FETCH_HEAD (or with no argument) doesn’t produce this message, it uses ‘remote-tracking branch’ or just ‘branch’ instead.
