Collapsing //file/name to /file/name violates POSIX (some systems use that
notation for remote machine shared drive access).  XBD 3.2 defines
absolute path as "A pathname beginning with a single or more than two
slashes", and XBD 4.11 agrees, so you are only allowed to collapse 3 or
more leading slashes.
