Non-quoted username mentions are broken; due to extra whitespace added to the end

Am I the only one seeing this??

The issue is that something is adding  
""
to the end of usernames. Quoted ones seem to end up linking properly, but unquoted ones look funky and don't link to the user's profile.

I've added some HTML-stripping code to functions.general.php:getAllMentions() (which I copied over from the latest github branch so that quoted mentions would work), so at least users are getting mentioned properly now. Quoted or non-quoted.

After insertion, before posting - here's what the inspected element looks like:

I'm starting to hit near the limits of my ability to debug this in any humanly-reasonable amount of time. I'm hoping that someone who is familiar with the javascript that controls the @ mentions and jquery.atWho library customization might have an idea. The function mentions Dane MacMillan as author?
