David, I see... And that is the key problem, then. Now I understand why the
spam with asterisks is so problematic. Consider the following example:

$ echo "no*goodword" | bogolexer -p -H
goodword

This could be a way for spammers to trick out  bogofilter forcing to count
good words as bad words. Am I right?
