Im having trouble wrapping my mind around the log file config option. 

1) I would expect it to replace the terminal rather than go on along side it (I can pipe to tee if I want to have my cake and eat it too)
2) I would expect to to debug or not based on the debug flag (which it ignores).

I _think_ that this is OK behavior (I can see a lot of reasons why you might want it this way) but I might take another pass at the wording of the option help string.
