>From a purely technical perspective, there is a major advantage to this
patch: it creates a "pure VFAT" filesystem, without a spurious filename
alias which still occupies namespace, hiddenly, and therefore could
cause an ill-defined amount of problems.  UMSDOS at least had the
decency to not expose its shortnames to a longname-aware OS.

However, as such it really should be paired with a "don't even recognize
the shortname if a longname exists" option.

It's also questionable IMO if this shouldn't be another FAT superdriver,
just as we have VFAT, MS-DOS etc. we could have "purevfat".
