title: Is there a Git config setting to auto-signed-off-by my commits?
body: <p>In some repos I want to always include "signed-off-by" messages in my commits (<code>git commit -s</code> not <code>git commit -S</code> which is for a cryptographic signature). Is there a <code>.gitconfig</code> value I can set to make this happen (so I can just type <code>git commit</code> instead of <code>git commit -s</code> every time)?</p>
