psql: Buggy interactions with wraparound in maximized gnome terminals.

This is probably hard to reproduce, but I entered a state where the
command I was writing was wrapping around at the 81st character while
in full screen, and the 1st character was being overwritten.This did
not affect the command sent to the server, but I would not have a way
to see what command I just entered.

I'm using ubuntu 18.04, the terminal is Gnome Terminal 3.28.2

Below is a short video showcasing the issue. I thought I had muted my
mic, but apparently I didn't, please enjoy my nation's anthem while
observing said bug.

Additionally, while researching this bug, I found a reproducible
variation of this bug:

1- Open a terminal at a normal size.
2- Write enough characters so that they correctly wrap around into a new line.
3- Maximize the window
4- Minimize it again

You will find that the command is visibly duplicated. Again this is
aesthetic, the command is not duplicated when it's sent to the server.
You can find a video of this bug below (I gotta learn how to turn
that mic off)
