Sorry,  Eric.  I didn't test it so far but now I installed it and
it looks like I have a few problems.

1)

  While rename(2) allows to drop the .exe suffix, mv(1) doesn't anymore:

  $ mv a.exe a
  mv: a.exe and a are the same files

  Expected result:

  $ mv a.exe a
  $ ls a*
  a

2) Even renaming doesn't drop the suffix:

  $ mv a.exe b
  $ ls b*
  b.exe

  Expected result:

  $ mv a.exe b
  $ ls b*
  b

3) And, as you noticed yourself, mv adds the suffix even if it wasn't
   given in the original filename:

  $ ls a*
  a
  $ mv a b
  $ ls b*
  b.exe

  Expected result:

  $ mv a b
  $ ls b*
  b

In theory, the only case which should append a suffix is this one:

  $ ls a*
  a.exe
  $ mv a b
  $ ls b*
  b.exe

All of the above problems also affect cp (and probably install).
