Graceful cancellation on long line with -S #260
Description
I use S as one of my configuration options, and I tried viewing a single-line 25MiB file. It was taking a few seconds (even with a hot cache) so I tried to cancel with C-c but that didn't work immediately either -- it took another few seconds. The behavior I would like is for it to cancel more quickly when interrupted. It cancels right away without S. I'm not sure if this is expected or not.
