    Fix kadmin script mode command-not-found error
    
    In ss_wrapper.c, if ss_execute_command() returns an error, we should
    call ss_perror() with *args as the third argument and not request
    (which is NULL).  Expand out the conditional into three commented
    branches for greater clarity, since the error-handling is no longer
    identical for the ss_execute_command() and ss_execute_line() cases.
