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.

Comece reproduzindo o comportamento do histórico com entrada parcial na REPL do branch principal do CPython no Linux, usando o exemplo sp do relatório. Compare os resultados da seta para cima com o comportamento esperado do histórico filtrado por prefixo; o problema estará resolvido quando apenas as entradas correspondentes do histórico forem exibidas e as entradas não relacionadas forem ignoradas.
