  Modified:    bin/sh    Makefile parser.c shell.h
  Log:
  Make the shell handle a null command in a &&/|| sequence correctly.
  The && and || tokens do also terminate a command, not only the
  newline.
  
  While i was at it, disabled trace code by default, it served no good
  purpose since it required the use of a debugger anyway to be turned
  on.  Instead, placed a hint in the Makefile on how to turn it on.
  
  This makes the shell ~ 10 % faster and ~ 4 KB smaller. :)
