Hi Ben and thanks for review.
I double checked and I can confirm the patch is ok.
Changes which are applied to rpc pointer within do_convert() and
do_need_conversion() function are local to
functions and not propagated to outside world. This is because rpc is
passed to command handler functions as
pointer and reference to the pointer. Therefore main() could not know rpc
has been changed inside command
