Stdout unless the PAGER env var is set.  Otherwise, I'd say still stdout
since the person can pipe it through a pager if they want, but you could
use the pager or be fancy and try to detect if stdout is a pty/tty
before using the pager.  Git pages by default and it bugs me because I
tend to use git commands in emacs shell windows and the pager makes a
mess.
