title: Who gets credit for a hand-edited patch file?
body: <p>A follow-up question to <a href="https://stackoverflow.com/a/11066487/1301972">my answer</a> about editing GitHub pull-requests asked whether editing the patch file directly before applying it would result in taking credit for the original author's work. Since it wasn't really part of the original question, I'm asking it here as a new question.</p>
