Cycle with default pager

[noahfraiture]

Hello,
I added delta as a pager but it's not perfect (it wraps line in a weird way to me) and I would like to be able to cycle with the default pager. However because I configured only delta, I can't cycle between pager, it seems that the default pager is not considered.
Is it something possible ? Else can I make a PR for it or is it by design ?
