I *think* that the buffer passed to yyinput or whatever is actually not at 
the beginning.  There is a case where the buffer is to be appended to when 
text is put off and then bubbled back up.  This is where I have been 
tracing for the past two days.

The buffer as passed by lex is some offset from the actual buffer.  I have 
no idea if there used to be a need to know where in the buffer you were, 
but lex figures where in the buffer it needs the next input.

to mean electronic messages designed to be read by an individual, and it 
can include Usenet, SMS, AIM, etc.  But if it is not all three of 
Unsolicited, Bulk, and E-mail, it simply is not spam. Misusing the term 
plays into the hands of the spammers, since it causes confusion, and 
spammers thrive on  confusion. Spam is not speech, it is an action, like 
theft, or vandalism. If you were not confused, would you patronize a spammer?
