If you go down that road, then you need another term to describe a path 
that has both.  Peter Dimov's [make_]absolute needs another name, because 
it has a postcondition that the returned path both "has_drive" and 
"has_root_directory".

IOW, there are three conditions we need nice names for:

    (1) Has a drive, volume, device, share, or file system name.
    (2) Begins at the root directory.
    (3) Both (1) && (2).
