That is way too magic for my liking. You can not predict what users want 
either. I for example like to see output immediately, and am prepared to 
use scrollback.

A simpler method that does not mess with the hg internals is to wrap hg 
in a bash function, like

function hg() {
    command hg "$@" | crufty_pager
}

where crufty_pager is a script that reads its input and if it finds more 
than 25 lines fires up $PAGER, and otherwise just writes them to stdout.
