Man, what a mess.

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4787931 has some
research on this.  It doesn't make it less of a mess, exactly; more
confirms that it really is a mess...

AFAICT, there is no right answer.  USERPROFILE and HOMEDRIVE/HOMEPATH
mean two different things.
http://www.ethereal.com/lists/ethereal-users/200108/msg00183.html
seems to argue that USERPROFILE is the one we want, but, eh, the whole
system doesn't make much sense...

I've just implemented:
  1) if MONOTONE_HOME is defined, use it
  2) if HOME is defined, use it
  3) if USERPROFILE is defined, use it
  4) if HOMEDRIVE+HOMEPATH are defined, use them
  5) whine at user

Is that good enough to make people happy?
