    application: Pass --command argument to shell
    
    Using the real shell, rather than splitting with g_shell_parse_argv(),
    means the command can contain shell metacharacters and syntactic
    constructs like
    
        kgx --command="ls *.txt"
    
    or
    
        kgx --command="if [ -e foo ]; then bar; fi"
