Excessive output when terminal isn't tall enough

[lheckemann]

When too many lines of progress indication are being printed, scrollback will explode. It looks mostly fine if you're not scrolling back:

but if you make the terminal taller or scroll up, you'll see a problem:

This can drown out valuable output from the build phase or similar.

A simple way to reproduce this is to run colmena apply keys with the following hive.nix, in a terminal less than 20 lines tall:

with import <nixpkgs> {};
lib.genAttrs (map (n: "host${toString n}") (lib.range 1 20)) (name: {
  deployment.targetHost = "dummy.invalid";
  boot.isContainer = true;
  deployment.keys.block-deployment = {
    keyCommand = ["sleep" "infinity"];
  };
})

This issue has apparently been known upstream in indicatif for a while:
