well, it means that we need to implement the pollout stuff for writting
our buffer back... 
not very complicated, but not the easiest stuff to start with

DwarfII shouldn't be on the TODO list. IMO, it's way better to integrate
PDB (and the like) symbol manipulation in gdb and use the proxy version
of winedbg

- for the up/down, it's already in there... (in fact, use the emacs form
of command ctrl-P ctrl-N
- if you really want up/down, you just need to change the mode of the
console (in winedbg.c) (or move this settings as a configuration option)
- implementing tab completion would require quite of work
	+ reimplement tab processing
	+ reimplement lexical analysis
  => I'm not sure it's worth it... for most commands you have shortcuts
which speed up things
