Yes, but the counterargument to that is: since you're replacing the old filespec with a completely unrelated path, who's to say that the old path syntax is any better fit than "host".
I think it would be best here to actually make this argument mandatory and force everyone to think about the correct syntax when constructing the object, but maybe that's a change for another day.

> Yup, llvm doesn't consider `C:` or `//net` to be absolute paths (as opposed to `C:\` or `//net/`. While this is debatable, it makes things consistent with drive names on Windows, which is why I added the net tests above.
Ah, I see.. I can certainly understand why `c:` wouldn't be considered absolute, but I'm not sure the same thing applies to `//net`. However, I think I can live that interpretation right now..
