[Amforth] documentation error

I am new to the forth world and i'm loving it. I was on the newark ( an 
electronics parts distributor ) a few months ago and they were selling 
avrbutterflys for 8 US dollars. So I bought a few and while thinking 
about what to do with them I found forth and fell into the rabbit hole. 
That being said, in the cookbook section/popular boards/avr butterfly 
section it gives an rtc example code. The problem is that the above loop 
should wait until those three registers are 0. If you leave a 0 on the 
stack you end up in an infinite loop, and yet surprisingly the +32kHz 
function that loop comes from works. Well if you dump the ASSR register 
value ( using .s ) you see that the first look at the register that the 
TCRTUB flag is set so the value on the stack is one and the loop ends. 
This is not what the exit condition you want for this loop. Those last 
three bits in ASSR should be 0 according to the data sheet for the 
atmega169 (and I also for the atmega328) before moving on. A simple fix is:

   begin
        ASSR c@
        1 2 lshift    \ TCN2UB
        1 0 lshift or \ TCR2UB
        1 1 lshift or \ OCR2UB
        and
        0=  \ add this line
    until

How would I submit this as a patch for the documentation?
Thanks,

ps used this loop to see the values on the stack
  begin
     ASSR c@
     1 2 lshift    \ TCN2UB
     1 0 lshift or \ TCR2UB
     1 1 lshift or \ OCR2UB
     bin .s cr hex
     and
     0=
   until
