The paginator should properly handle too long lines

[sentry-io]

We often have some features feeding too long lines to the paginator, leading to a cryptic RuntimeError. The paginator should properly handle those.

Here is a Sentry issue showing this error from the !raw command.

Rather than patching each feature that tries to use the line paginator, I think it's a much better idea to make the paginator handle such inputs gracefully.

This is using the default paginator rather than our LinePaginator, which does properly handle lines that are too long. As mentioned, this is a duplicate anyway, so I'm closing it.
