Yes, that's right.  The documentation is pretty inaccurate.  What 
actually is supposed to happen is that you get the actual path, with 
forward slashes in it, unless it contains spaces:  then you get the 8.3 
version.  So John's path has no spaces, and doesn't get converted to 
8.3.  True 8.3 would also have uppercase PROGRAMS, and only one dot in 
R-2.13.0 (I forget how that is converted).
