MS isn't consistent across operating systems.  W2000 doesn't handle 8.3 names
with mixed case as well as 95 or 98 does.

Here is a listing from w2000
D:\HOME\Faculty\rmh\hh\dsgn>dir/x
 Volume in drive D is APPS
 Volume Serial Number is C0C1-3AB6

 Directory of D:\HOME\Faculty\rmh\hh\dsgn

The /x gives two columns, the 8.3 names and the long names.
Notice that the 8.3 name is empty when the long name is 8.3, no matter
what the case of the long name.  When the long name is not 8.3, then
an 8.3 abbreviation is generated in all caps.

When these files are copied to floppy disk, then the long names and their
abbreviation are both copied to the floppy.  The 8.3 names are copied to
floppy after being upper-cased first.  This is a change from W95 and W98.
In W95 and W98 there are always two columns in the dir listing.  The
8.3 column is upper case and the long name is whatever the user says it is.
When W98 files are copied to floppy both names are copied and the floppy
retains the case distinction.

Is there any way emacs can always write both columns, even when W2000
won't do it by itself?  This would save lots of aggravation when I move
files between W2000 and W98 systems.
