You haven't been watching the threads that I participate in. :-)

Consider the change from: 
   Re: [tlug] Nasty Problem: searching for strings that span newlines [1]
to: 
   [tlug] Following Threads in Email [2]
by yours truly. 

It's OK to have a radical change in the message content in a thread, 
as long as the replier is actually replying to _something_ in (or about) 
that which they are replying to. 

If Ian had started a new thread, it would have broken the reference 
to what he was taking exception to. His continuation of the thread 
was appropriate. My changing the subject was also appropriate.

Minor stuff beside the point: 

In [1], Ian should have quoted _something_, particularly my subject, 
and Ian should have changed the subject himself, but understandably 
did not because he thought it wrong to do so (which was his point!).
