Should it report the name of the temporary file in that case, or should 
it fail if it's not being run with a capture pipe (i.e., if it's not 
being run by Ethereal, which would read the temporary file name from the 
capture pipe), so that you have to use "-w" when capturing from the 
command line?  (I.e., is the ability to capture to a temporary file 
useful when it's run from the command line?)
