/* Svprintf:
 *
 *   Returns: count of bytes sent, which may be 0
 *
 *   This function is like vprintf; it takes a Socket pointer, a format
 *   string, and an argument list.  Note that it actually "prints" the
 *   string into a local buffer first of PM_BIGBUF bytes (originally 1024
 *   bytes).  So, please insure that you don't put more info than will fit
 *   into PM_BIGBUF bytes!  It then squirts the resulting string through
 *   a call to Swrite.
