Took a hint from _xargs...  Attached patch incorporates:

1. my fix to allow multiple '-u/--unset=' args
2. Ingmar's documentation fix
3. the fix to complete arguments to the command passed to 'env'

Does not include the '(--unset= -u)' Ingmar had prepended to the '-u' 
line.  (I think that would explicitly prevent multiple -u/--unset args.)

Best,
Ben
