    sh: Reduce unnecessary forks with eval.
    
    The eval special builtin now runs the code with EV_EXIT if it was run
    with EV_EXIT itself.
    
    In particular, this eliminates one fork when a command substitution
    contains an eval command that ends with an external program or a
    subshell.
