Sorry, I'm not following the chronology, as the calling script cannot possibly 
receive the selected time zone until after tzselect outputs the tail dialog. So 
if the calling script knows that the user has confirmed, it can filter out any 
further stderr output it doesn't want; and if it doesn't know, it shouldn't care.

Perhaps you could give a runnable example of a calling script to illustrate the bug?
