Potential buffer overrun in function init_send_receive_history

[npat-efault]

In your code, in picocom.c, line 676, you should use "strcpy" instead of "strcat".
As you get "send_receive_history_file_path" from a "malloc", there is no guarantee that it will be zeroed-out.
This, or you should change "malloc" to "calloc".
