title: Maximum commit message size
body: <p>Is there any size limit to the Git commit message?
  I searched trough the web but cannot find any relevant mention about this except <a href="http://lists.busybox.net/pipermail/busybox-cvs/2010-March/030975.html" rel="noreferrer">this one</a>.</p>
  
  <p>However, that one does not answer my question.</p>
