[latexrefman] What does « While @code{\message} allows you more control over formatting interaction lines » mean ?

[Karl Berry]

    I am afraid I don't know what an « interaction line » is ?

Jim just meant the lines output to the terminal during an interactive
run. That's what \message does, after all. I agree it's not the clearest
phrase.

I just reworded (by removing it :), and a couple other places in
that section. --thanks, karl.
