I have an explaination. His exec line needs my $qcmd string as well,
thus:

  #!/bin/bash
  qcmd=
  for arg
  do  qcmd=$qcmd`printf " %q" "$arg"`
  done
  exec -l "$SHELL" -c "exec $qcmd"

This skips login(1) and possibly addresses Harald's issue with = signs
in the zeroeth argument. It doesn't address the generic syntax issue
he raises.

I have an idea for that for my next post (have to do a machine shutdown
first:-)

Cheers,
