If you took a look at it now, you might not need to ask this <0.5 wink>.

In short: yes.  In reality, we skip any tokens less than three  
characters in length, and there are also many tokens from the headers.

Look for mention of "character n-grams" in the comments in  
tokenizer.py for discussion about this.  In short, 'words' work  
better and have the added bonus of resulting in (mostly) human- 
understandable tokens.

Your example (assuming there are no header tokens) would either be  
spam (another spam using these embedded words has already been  
trained), or unsure (they have never been seen before).  Your example  
is also extremely unclear - it does a very poor job at selling, which  
is the whole point, after all.  So a spammer gains little, and has  
lost a lot.
