If there is no further work (and I don't see any), is it
not appropriate to "exec" the last step, thus eliminating
one extra process (the shell)?  Viz:

case "$pagefile" in
*.bz2)
        exec bzcat "$pagefile" | "$PAGER" ;;
*.gz)
        exec zcat "$pagefile" | "$PAGER" ;;
*)
        exec "$PAGER" "$pagefile" ;;
esac
