Yah we can put the mark at the end of the line. I wasn't sure if there
was a strong motivation to avoid extending the the width of each line,
as sometimes people prefer to try to keep it close to 80 char as
possible. I think right now, it was close to that, but might be a little
over already. I can switch to that though, as it is less likely to break
any automatic parsing scripts.
