I'm at work now and can check a windows machine.  I looked in the
directory specified by %USERPROFILE% and found numerous files and
directories beginning with a "." dot.  Most were from programs developed
originally on unix systems but the precedent is there.

BTW, I use the following algorithm to determine a home directory.  This
probably fails on older windows systems that don't set USERFPROFILE,
HOMEDRIVE or HOMEPATH.  And expanding "~" fails on anything without HOME
defined, so I need a better "last resort".  Suggestions welcome.

    def find_home
      ['HOME', 'USERPROFILE'].each do |homekey|
	return ENV[homekey] if ENV[homekey]
	return "#{ENV['HOMEDRIVE']}:#{ENV['HOMEPATH']}"
