Feature or enhancement

Proposal:

Currently, if you set abreakpoint() in your code, and exit withq orctrl+D, the output is just ugly:

Traceback (most recent call last):  File "/Users/gaotian/programs/cpython/example.py", line 11, in <module>    while True:          ^^^^  File "/opt/homebrew/Cellar/python@3.12/3.12.6/Frameworks/Python.framework/Versions/3.12/lib/python3.12/bdb.py", line 90, in trace_dispatch    return self.dispatch_line(frame)           ^^^^^^^^^^^^^^^^^^^^^^^^^  File "/opt/homebrew/Cellar/python@3.12/3.12.6/Frameworks/Python.framework/Versions/3.12/lib/python3.12/bdb.py", line 115, in dispatch_line    if self.quitting: raise BdbQuit                      ^^^^^^^^^^^^^bdb.BdbQuit

It makes no sense to print a trackback of an exception just because I want to quit pdb and stop debugging. Now that we have an indicator for inline mode, we can deal with this.

What I propose is - for inline mode debugging, any quit attempt(q,ctrl+D, etc.) will trigger a confirm prompt (likegdb orlldb), the user can say no and go back to debugging, or they can confirm and quit the program.

There are a few design details which I will list in the following PR.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
