Now that I'm using U-Boot 2023.04 I noticed that this introduces a (cosmetic)
regression: The autoboot countdown in bootmenu is now longer re-written, but
instead the last menu item line is continously appended like:

U-Boot consoleHit any key to stop autoboot: 3 Hit any key to stop autoboot: 2

To regain the previous behavior one should change the line to
#define ansi 1

To me this looks a bit unfinished, as if there was some sort of
probing of the terminal capabilities supposed to happen but then
this has never been implemeneted...
