39.39 is supported on any volume format on any VMS release from the
last couple of decades or more.  Longer names are supported on the
newer volume format (ODS-5) on newer releases (where newer means one
decade or so).  We could desupport the older versions if limiting to
39 is really getting in the way of something important, but that seems
pretty long to me (I believe one file from CPANPLUS currently breaks
this, and means the distribution tarball can't be unpacked on VAX
without removing that file first).

I think no distinctions solely on case applies as much to default
Windows and Mac OS X filesystems as to VMS.
