If an answer uses a link with the default format (using `[link text][1]`) and later `[1]: http://somelink.com/` then when a moderator does convert-to-comment it doesn't become a link.

It should convert to `[link text](http://somelink.com/)` without the moderator having to go edit the comment.

Here is the answer text to [this question](https://money.stackexchange.com/questions/8215/why-do-non-electronic-stock-exchanges-still-exist) that was converted to a comment:
