That is standard behaviour for most modern shells.
The readln() function has nothing to do with libreadline.
The problem you are seeing is due to the shell you are using and the
key binding options you have assigned or defaulted to in the shell
and/or the terminal emulator. It has nothing to do with FPC.
So you are saying, that cmd.exe is monitoring what am I typing, and
when test.exe is waiting on `readln(s)` and I press UP, then cmd.exe
somehow paste to STDIN what I typed 1 EOL before?
Yes, that is correct.
If you run the program twice, you'll see that you can "scroll back" even
to what you typed in the first run of the program; This is clear proof
that it is not the program itself which does that.
