`less` is a better default if and only if it's available - in my (limited) research, `more` was the only pager we can be sure exists. The way git handles this is that the default-default is `less`, but you're one compile-time config knob from changing it to something else. Same for the default-default LESS environment variable.

We can probably get away with `less` as the default-default, but we should still strongly encourage packagers to do the right thing with a config rather than patching the code (since they don't need to.)
