This seems to allow a lot more than just scp.

scponly.c:process_ssh_request

        /*
         *      request must be one of a few commands.
         *      some commands must be exact matches.
         *      others only require the beginning of the string to match.
         */

        if ((exact_match(request,"ls")) || 
                (NULL!=strend(request,"ls ")) || 
                (exact_match(SCP2_ARG,request)) || 
                (NULL!=strend(request,"scp ")) ||
                (exact_match(request,"pwd")) ||
                (NULL!=strend(request,"rm ")) ||
                (NULL!=strend(request,"ln ")) ||
                (NULL!=strend(request,"mv ")) ||
                (NULL!=strend(request,"chmod ")) ||
                (NULL!=strend(request,"chown ")) ||
                (NULL!=strend(request,"mkdir ")) ||
                (NULL!=strend(request,"rmdir "))) 
                        exit(exec_request(request));
