pager: set some environment variables if they're not set
Git did this already [1] [2]. We want this behavior too [3].
This provides a better default user experience (like, supporting colors) if
users have things like "PAGER=less" set, which is not uncommon.
The environment variables are provided by a method so extensions can
override them on demand.
