Using -r -T -J works, in that it generates correct file names for at
least one version of Windows, I have just confirmed.  I'll test a Mac
later on, but I imagine it should work.  My file names in this example
are only 20 character plus an extension, but that's enough to confirm
that I'm not seeing 8.3.  It's not enough to confirm >31 character
compliance.

Joliet (-J) provides 31 char file names.  The -T flag provides a
translation table.  It's not clear to me which should supersede the
other, but both is enough.

By the way, -pad is the default and so no longer needs to be
explicitly specified.  The -d flag is advised against on the man page,
as it violates the ISO 9660 standard.

Thanks much to all.
