commit 8ce85065a9e0cc4d8ac6d7b13ef99f7177d116a9
Author: Antonio Borneo <antonio.bor...@foss.st.com>

    helper/command: drop unused variables
    
    In both functions script_debug() and script_command_args_alloc()
    the variable len is never used, and Jim_GetString() does not
    mandate it.
    
    Drop the variable and pass NULL to Jim_GetString().
