native process 877 In: main               L13   PC: 0x40056f=20
Temporary breakpoint 1, main () at hello.c:3
(gdb) n
(gdb)=20
hello8
hello9
hello10

...

That is, from top to bottom:
- src window
- status window
- cmd window
- output window
...

This fixes the problem that:
...
(gdb) next
...
followed by <enter> produces very briefly:
...
(gdb) next
hello
...
before being overwritten by the following prompt:
...
(gdb) next
(gdb)=20
...
