Code review comment for lp:~jamalta/launchpad/relatedbugs-118609

This looks great, thanks for doing it!

I have only one comment. The description in the doctest is a little stylistically off. It should read like documentation. Can I suggest an alternative?

  The person bugs page can be accessed without being in the bugs
  site, yet all the menu links point to the bugs site.

There's no need to mention the bug number.
