Bug report

Bug description:

According to thedocumentation:

With no bpnumber argument, commands refers to the last breakpoint set.

I think the intended meaning should be the last available breakpoint. However, when using thecommands command without specifying a breakpoint number, if the most recently created breakpoint has been deleted, the current behavior throws an error stating "Breakpoint N already deleted".

main.py:

foo=1bar=2
