[ESS] Finding all versions of R on Windows when R not in default directory

[Richard M. Heiberger]

Fortunately it got through to the OP.  Here it is again, this time renamed
as a .txt file.

This is not registry based.  The default continues to use the default
location of
the R installation.  The alternative lets the user define a new starting
position instead
of Program Files or its equivalent in the Environment Variables.
