From: Johannes Schindelin <redacted>

When formatting the commit message for merge commits, Git appends "into
<branch-name>" unless the current branch is the default branch.

Now that we can configure what the default branch name should be, we
will want to respect that setting in that scenario rather than using the
compiled-in default branch name.
