I started looking into https://code.google.com/p/dart/issues/detail?id=8343, but
it seems I won't be able to fix it without some dart:io support.

In the meantime, I have a test for the bug that currently fails.

Could you make all "s into 's?

Do we want one of these for broken links within "packages" as well?

Pub doesn't really have a well-defined guideline for when to prefer one string
style or another. We need to figure one out, but we haven't. Right now, it's
just a mixed bag.
