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).
