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?

breakpoint() から入る pdb セッションを起点にして、その履歴がメイン REPL の履歴とともにどのように扱われるかを追跡します。pdb 固有のコマンドがメイン REPL の履歴に表示されなくなり、pdb の開始時に issue が意図している最近の REPL エントリへのアクセスが維持されれば完了です。
