pdb history file should be different per default, not the same with main repl

Feature or enhancement

Proposal:

After quitting from debug session (triggered by breakpoint()) to the main repl, I've it's history filled with a bunch of pdb-specific stuff. Usually (always?) these lines have an invalid syntax for python.

Maybe it does make sense have access to recent repl entries after starting pdb, but hardly the main repl's history should have access to pdb history. That should live in a separate file.

Has this already been discussed elsewhere?

从通过 breakpoint() 进入的 pdb 会话开始，追踪其历史记录如何与主 REPL 的历史记录一同处理。完成的标准是，pdb 专用命令不再出现在主 REPL 的历史记录中，同时保留 issue 预期的、在启动 pdb 时访问最近 REPL 条目的能力。
