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?

從透過 breakpoint() 進入的 pdb 工作階段開始，追蹤其歷程記錄如何與主要 REPL 的歷程記錄一同處理。完成的標準是，pdb 專用命令不再出現在主要 REPL 的歷程記錄中，同時保留 issue 預期的、在啟動 pdb 時存取最近 REPL 項目的能力。
