Jeff King 69a8b7c741 merge: indicate remote tracking branches in merge message
Previously when merging directly from a local tracking
branch like:

  git merge origin/master

The merge message said:

   Merge commit 'origin/master'

     * commit 'origin/master':
       ...

Instead, let's be more explicit about what we are merging:

   Merge remote branch 'origin/master'

     * origin/master:
       ...

We accomplish this by recognizing remote tracking branches
in git-merge when we build the simulated FETCH_HEAD output
that we feed to fmt-merge-msg.

In addition to a new test in t7608, we have to tweak the
expected output of t3409, which does such a merge.
