The above happens even when NameNumericTail is left at its default value 
of 1.  So even users who don't change the registry at all will hit this 
problem.

Btw, Windows doesn't mess up the filenames which use all the 8+3 
characters; they just have identical long and short names (except, maybe, 
for the case, if you cared to rename them).  This is true even if 
NameNumericTail is 1.

It is still wrong IMHO to rename only one part of the filename.  If a 
file can be referenced by any of the two names, they both should be 
changed when the file is renamed.  Otherwise, if you reference the file 
by the wrong name, it was not renamed.

How is it broken to rename a file and expect it to change its name?
