Thanks for the explanations.  Could you please look at nlinum.el (in
ELPA) and see whether its solution to this problem is better, or at
least not worse, and satisfies the needs of darkroom-mode?  If so, I'd
rather we adopted the nlinum solution in linum as well.

If there's something to be done for coexistence with nlinum, I'd
prefer to have a solution that works with both linum and nlinum.

Thanks.
