The New REPL Command History Does Not Honor Partial Text

Bug report

Bug description:

Let's say I fire up the REPL and start with the following:

>>> spam = 1
>>> ham = 2
>>> eggs = 3
>>> sp

At that point, I can up-arrow to scroll through my REPL command history. Normally with that partial sp on the line, hitting up-arrow once will immediately present spam = 1. Hitting it again will do nothing (since there are no more matching lines).

With the new REPL, it presents eggs = 3. Hitting it again will present ham = 2, and again it presents spam = 1. I'd rather it keep doing what it did before.

Comienza reproduciendo el comportamiento del historial con entrada parcial en la REPL de la rama principal de CPython en Linux, usando el ejemplo sp del informe. Compara los resultados de la flecha arriba con el comportamiento esperado del historial filtrado por prefijo; el problema se resuelve cuando solo se muestran las entradas del historial coincidentes y se omiten las entradas no relacionadas.
