Bash uses readline, and readline can delete the word to the right of the cursor with "kill-word".
The problem is in recognizing the keypress of control-delete. When I press them in bash, "5~" is output on the screen. I could just bind for this, but it...

As you say, it's a bug.
Now this is clearly code from crazy town.
() { try { if( object != NULL ) { delete object; object = NULL; } } catch(...) { } }
Since your list element.

How does the delete operator work? Is it better then free()?. Also if u do ptr=new char[10] , then delete using delete ptr , how does the pointer know how many locations to delete.

There is an internal "magic" in delete operator.
Under C++, you are encouraged to use new / delete over malloc() / free() .
There is only delete operator, free exist only as function.

I remember someone saying if you create a class through a lib you should destroy it through the lib. So does this mean i shouldnt call delete? i should call myclass.deleteMe() instead? would overloading delete solve the problem?

I know that I am supposed to use delete [] when I used new [], so using auto_ptr with new [] is not such a bright idea.
However, while debugging delete [] (using Visual Studio 2005) I noticed that the call went into a function that looked like this:

The behaviour might even change between compiler versions.
Just because they might work the same now, doesn't mean you can necessarily treat them the same shouldn't assume that delete and delete[] do the same thing.

While not very efficient, you can force your delete....
Something like:
Photo.objects.filter(name='something').delete()
If that's the case, that will not call your custom delete method since it uses the delete method on a queryset.
