  struct ck_p is defined in ckcker.h and has 10 members -- packet
  length, window size, control-char prefixing options, filename collision
  options, pathname stripping options, which are kept on a per-protocol
  basis.  These are, in general, duplicates of protocol-specific global
  variables.  The relevant SET commands set the values in both places,
  depending on what the current protocol is.  Whenever we switch protocols,
  we set the global variables to whatever is in this struct for that protocol.
