Make the various places that determine the user's "home directory"
consistent. On Unix we now always consult getpwuid(); $HOME isn't used at all. On Windows the code currently consults $USERPROFILE, or $HOME if that's not defined, but I expect this will change as soon as the win32 hackers come to a consensus. Nothing done yet about changing the file names used underneath $USERPROFILE.
