Is "Merged in" a commit message created by bitbucket, or git?

Question

The style guide "How to Write a Git Commit Message" section 5. Use the imperative mood in the subject line states that git itself uses the imperative mood:

The imperative can sound a little rude; that's why we don't often use it. But it's perfect for git commit subject lines. One reason for this is that git itself uses the imperative whenever it creates a commit on your behalf.

For example, the default message created when using git merge reads:

Merge branch 'myfeature'

And when using git revert:

Revert "Add the thing with the stuff"

This reverts commit cc87791524aedd593cff5a74532befe7ab69ce9d.

Or when clicking the "Merge" button on a GitHub pull request:

Merge pull request #123 from someuser/somebranch

However, on a git repository on bitbucket, I encounter the indicative mood:

Merged in feature/123 (pull request #1234)

Is this a message created by bitbucket as opposed to git?

Answer 1

From looking at my team's branch, when someone merges their own PR, you see

"Merge branch 'branchName' of bitbucket.org...".

When someone merges someone else's PR, you see

"Merged in teamName/repositoryName/branchName"
