Known upstream issue, still no behavior change in the upcoming 4.2.25:
http://savannah.gnu.org/bugs/?func=detailitem&item_id=13041

Also, a POSIX interpretations request was recently raised:
http://www.opengroup.org/austin/mailarchives/ag/msg08430.html

- -i implies -l (or in terms of their POSIX replacements, -I implies -L),
while -L and -n are mutually exclusive.  Whichever you specify first will
be cancelled by what you specify second.
