Nowhere in our API do we promise that the path returned on the Path:
line will be relative or absolute. We just claim that it will be a
path to the item. If people were relying on some implicit guarantee
that that path would be relative to some root, I don't think they have
a valid complaint.

I'd like to avoid info-item-proliferation if at all possible, and
given the lack of explicit absoluteness in the docs about the Path:
line, I don't think we need to add an additional line.

Yeah, we're going to have to rev the info interface anyway, for the
reasons you describe as well as the fact that the existing one is
pretty much a rebranded entry_t. I've got no issue with explicitly
declaring the returned path as absolute in the new callback, and I see
that you've implemented this in r39618.

(Wow, things sure are moving fast! A guy commits something before
going to sleep, and he wakes up to find his bugs fixed. :) )
