mawk in Ubuntu 20.04

Oh and it’s a pre-release snapshot; 1.3.4 is apparently not quite released yet. Or Tom Dickey doesn’t want to publish a formal release because he just continued development but isn’t the formal developer.

But good/sad to see he’s picking up another project… he also develops ncurses, cdk, xterm and lynx, and except cdk I use them daily… here’s to hoping fixes there won’t be less frequent now ☻
