Because external system hardware and software may perform the ACCEPT 
function, when a line terminator is received the action of the cursor, 
and therefore the display, is implementation-defined. It is recommended 
that *the cursor remain immediately following the entered text* after a 
line terminator is received.

Which is very elegant, but unfortunately with a standard Windows console 
an absolute swine to implement. Using file reads through stdin, Windows 
treats the enter key as a CR LF, and moves the cursor appropriately. A 
quick straw poll:

Does your favourite Forth do this (the > and < are meta chars to 
indicate input and output, the underscore is the cursor caret)

   >1 2 3 .s
   <[3] 1 2 3  ok[3]
   <_


or this?

   >1 2 3 .s [3] 1 2 3  ok[3]
   <_


And which is preferable?
