Copy this post http://xenforo.com/community/threads/foobarbazbazingaaaaaa.31440/#post-388613 to your clipboard and and insert it into the editor (i think this should also work with this bugreport because of the inserted link^^
as you see, the "space" before the link is gone...
It's happening ONLY with links, which are very long and placed because of their lenght in the next line.
Edit: it's whitespace and not blank space, or? (sorry, pls change title if it's wrong)
