less: update line input so that it doesn't interfere with
screen update. Makes "man bash", [enter], [/],
<enter search pattern>, [enter] more usable - manpage
draws as you enter the pattern! Yay!!
less: fix bug where backspace wasn't actually deleting chars
less: "examine file with empty name" doesn't abort anymore.
libbb: add "all fatal signals" mask.
