Yeah, I had to come up with some kind of "known trailers" list for what 
I call "non-person" trailers. It's easy to recognize a sign-off trailer, 
because it almost always follows the same format:

[\w-]: Name Here <email@here>

However, non-person trailers can be anything and we were routinely 
hitting false-positives whenever someone did stuff like:

See: https://foo.bar/baz
Example: https://foo.bar/baz
Ugh: https://foo.bar/baz
WTF: https://foo.bar.baz

Okay, there is a fix in master and stable-0.6.y that adds BugLink to the 
list.
