I guess we could, although that's a bit messier with respect to tests. (Also, perhaps it kinda loses a little bit of distinction between whether the path actually was specified as an absolute path or not - which probably isn't important?)

In all honesty, it was just the quickest solution I had for making this clearer in tests; I also considered wrapping the path in quotes, which makes it clear that we have one entry with an empty path. But Clang's printing of include directories is a similar feature, which doesn't quote the paths, so I felt it was better to go with consistency with that.
