It's not immediately obvious, at least to me, so I think this should be
documented.  Also I think error should be used for the message instead of
warning as the requested task is not performed. The message could be more
helpful too:

(gdb) d 1.1
This breakpoint cannot be deleted on its own.

I don't want to detract from the fact that you have contributed a major
patch but I think you should document your own changes.  This is also a
good idea because you understand the changes best.

Yes, thanks.  It seems strange to me that the return type needs to be
specified.  I thought with overloading, people talked about signature which
is determined by the name and arguments but not the return type.
