I can't tell if this is first class quality trolling or not :) But no, the nl2br() will not change this (imagine the backwards compatibility break). The reason why lynx has this option is probably to preserve screen real-estate as many website are silly and use <br> tags to wrap content around images.. which you don't see in lynx anyway. -Hannes
