Code review comment for lp:~benji/launchpad/add-launchpadlib-examples

It seems like if we're going to put that cross-reference in one place, we should mention it for every single link to a hosted file. But since the goal here is simple cleanup, and this is definitely an improvement, (and I don't actually want to mention it every single time) I'm not going to press the issue. Let's see how users respond and take it from there.
