I use the following "executable" for paging output for applications
called from within Emacs, and it _is_ jerkier than really desirable.

#!/bin/sh
TMP=`mktemp -t emacs-pager.XXXXXX`
trap "rm $TMP* 2>/dev/null" 0
echo '-*- mode: view; auto-revert-interval: 1; mode: auto-revert-tail; 
view-exit-action: kill-buffer -*-' >"$TMP"
exec 5<&0 <&-
cat "$@" <&5 >>"$TMP" &
eval "${VISUAL:-${EDITOR}}" '"$TMP"'
