[pito <pi...@vo...>]

the amforth issues one additional SPACE and that creates an issue
with Mosaic when editing the line and using backspace. The fix - do
comment out the XT_SPACE below:

...
PFA_ACCEPT5:
.dw XT_DUP        ; ( -- addr k k )
.dw XT_EMIT       ; ( -- addr k )
;.dw XT_SPACE     ; ( -- addr k ) <<<<< 20101026 by Pito
.dw XT_EMIT               ; ( -- addr ) 
....
