title: Can I make fast forwarding be off by default in git?
body: <p>I can't really ever think of a time when I would use <code>git merge</code> rather than <code>git rebase</code> and <em>not</em> want to have a commit show up.  Is there any way to configure git to have fast forwarding off by default?  The fact that there's an <code>--ff</code> option would seem to imply that there's a way, but I can't seem to find it in the documentation.</p>
