126.96.36.199.5 The Version part of a Logical Pathname Namestring
Some file systems do not have versions.
Logical pathname translation to such a file system
ignores the version.
This implies that a program cannot rely on being able to store
more than one version of a file named by a logical pathname.
If a wildcard-version is specified,
it parses into :wild.
