    sh: Reduce one level of evaltree() recursion when executing 'case'.
    
    Free expanded case text before executing commands.
    Remove impossible evalskip checks (expanding an argument cannot set
    evalskip anymore since $(break) and the like are properly executed
    in a subshell environment).
