Funny -- I see that you use it to create line_iterator -- which was exactly 
the motivation for eof_iterator. My version of line_iterator is at:

I still don't understand which design, yours or mine, is better. It seems mine 
allows to create iterators with smaller number of lines, but maybe there's 
something else.

The question arises because eof_iterator is already in CVS as part of 
program_options, and we surely can't add them both to iterators library....
