    The 'NameNumericTail' trick can cause some problems though.  Here's an
example of why I turned NNT back on:

Make 2 files, on named "a.cpp" and another named "a.cpp~" (I was using emacs
when I discovered this), the SFN's for these files will likely be "a.cpp" and
"a~1.cpp".  Now try copying both files to another directory.  There is a 50%
chance that one of the files will dissapear!
What happens is that if the "a.cpp~" file is copied first, it will have a
short-filename of "a.cpp", and then when the other file is copied, DOS decides
to overwrite "a.cpp~" with "a.cpp" because they have the same SFN.
