One possible problem with this patch, I realize now, is that if you
navigate backward ('l') and then visit another link there, the new page
is added to the very end of history rather than the immediate next
position. This would be confusing if you, then, navigate back and find
that it's not the page from which you followed the link. Perhaps the
original code was a hack around this?
