Extra "Embed quote" and/or "Asked to answer" text at the end of answers

[csu]

For the 'answer' values of answers (result["answers"][0]["answer"]), there is sometimes an extra "Embed Quote" and/or "Asked to answer" text appended to the end.

Reproduce: GET http://q.goel.im/url=https://www.quora.com/Google/What-are-the-changes-made-to-the-host-matching-phase-for-Google-Summer-Internships-from-2013-to-2014

Result (excerpt):

{
  "answer": "A2A.As far as I know, the process has not changed between last year and this year.Embed QuoteAsked to answer by Anonymous.", 

While answer_html does contain the answer without the extra text, I don't think this is the expected behavior for answer.
