[PATCH] merge: indicate remote tracking branches in merge message

From: Jeff King <peff@peff.net>
Date: Aug 9, 2009, 06:59 UTC
Message-ID: <20090809065936.GA24112@coredump.intra.peff.net>

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.

This is a repost of

  http://article.gmane.org/gmane.comp.version-control.git/119909

which got no response from you. I think it is a good idea, but I am not deeply committed to it. I mainly want a yes or no so I can clean it out of my patch queue.
