Joerg Wunsch 47a052e00f 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. :)
