I'm not sure what is being discussed.  Is it that the two above lines
are kept, or that one of the two is removed as a duplicate?

And why is the other behavior better?


        Stefan "To my layman's eyes, the two lines are equivalent, just
                like "* GDB: (gdb)" and "* Gdb: (gdb)" and should be
                collapsed into one"
