Yep, I hit it as well, and I do not really know how to do it. Maybe
something much more complex, along the lines of (hehe!):

  CT_DoItInASubShellSoVariablesDoNotEscape
  while true; do
    case "$1" in
      *=*)  eval export "$1"
            CT_DoLogThisFsckingVariable ALL "$1"
            shift
            ;;
      *) break;
    esac
  done
  CT_DoExecLogAsUsualThisCmdlineWithoutVariable ALL "$@"
