The shell script /usr/bin/nohup uses `$*' where it should use `$@';
this breaks things like `nohup sh -c "echo foo"' because the quotes
get lost.

Moreover, it insists on sending stdout and stderr to the same place,
even if they were both redirected; and the destination is either
nohup.out or the existing stdout, but the decision is based on the
status of *stderr*.  (So that, e.g., `nohup cmd 2>/dev/null' will 
actually leave its output at the terminal.)

It might also be mentioned that `test -t >&2' is a bit obscure; the
notation `test -t 2' or `[ -t 2 ]' is more transparent, if indeed
this is the desired effect.
