This makes it easier to get *any pager* in the number of places we do.
Unfortunately:
1. It can't just execute the pager because that might block
2. We can't really set the necessary options for less here
so they still need to be set outside.
This
Fixes #10074
by falling back to `cat` in that case. We could also decide to abort
instead of using a non-pager, but for history that's probably fine.
