I didn't notice it either in the past, but I don't remember when
the previous error occurred.

I think that the incorrect newlines could be due to a different
terminal mode.

I don't remember what I did after, but I either restarted aptitude
without looking or I hit Ctrl-D to end the root shell and my precmd
zsh hook fixed the terminal mode (very useful!) with rmacs + sgr0; I
also have the "ttyctl -f" feature (which should fix the echo mode).

BTW, shouldn't aptitude-curses fix the terminal mode (a bit like what
my precmd zsh hook and "ttyctl -f" do) between each apt.conf.d hook?
