Hi!

This is not correct. There actually *is* a convention:

versioning
versioning.~1~
versioning.~2~
versioning.~3~
versioning.~4~
versioning.~5~
versioning.~6~
versioning.~7~
versioning.~8~
versioning.~9~

The above was generated by 'le' but many Editors use it. Works fine
with XEmacs on Windows as well :->

Which becomes obvious when mounting the CDROM as plain ISO 9660 when
it actually uses Rockridge extensions or a Joliet filesystem.
