stderr redirecting considered harmful.

[Ryan C. Gordon]

This line in image/setup.sh:

        "$setup" "$@" 2>/dev/null

Breaks pagers in the console UI (tried both "more" and "less"). I don't
really understand why, honestly, but it does.

Is it safe to remove the stderr redirect?

(by, console_ui.c in CVS now respects the $PAGER envr. variable, and
defaults to "more" if it isn't set).
