This should be the new default on Windows as of Cabal-1.8.0.4 /
cabal-install-0.8.4. Existing cabal config files will not be updated,
but people installing for the first time should get this default.
Perhaps Ralph can double check that for us.

Ralph: note that this stuff with the config only applies if you run
the "cabal" program, rather than compiling and running "Setup.exe".
The latter is more low level, does not use any config file and has
different defaults. Easier to stick to the "cabal.exe" program.
