> Support constructs like:
> {noformat}
> set a=b ; (set a=c; echo $a); echo $a
> {noformat}
> This should create 2 shells. and result in:
> {noformat}
> c
> b
> {noformat}
> Executes as follows:
>  * set a=b
>  ** set a=c
>  ** echo $a
>  * echo $a
> Intenally the sub-shell is delegated to the builtin subshell command.
