grub2 code

[Robert Parnell]

Hi

I was just looking at the grub2 source code and saw that
https://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/grub2/trusty/view/head:/TODO
<https://bazaar.launchpad.net/%7Eubuntu-branches/ubuntu/trusty/grub2/trusty/view/head:/TODO>
says to contact with questions.
I was looking at the source because I encountered a bug on my machine 
that has been previously reported
(https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1027694) and
thought I'd have a look to see if I could find the problem.
So I have 2 questions:
1. Is the code on launchpad the up to date code?
2. Line 177 of
https://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/grub2/trusty/view/head:/grub-core/boot/i386/pc/startup_raw.S
<https://bazaar.launchpad.net/%7Eubuntu-branches/ubuntu/trusty/grub2/trusty/view/head:/grub-core/boot/i386/pc/startup_raw.S>
is a function that flushes the keyboard buffer, could this be what is
causing the bug?

Sorry if 2 seems like a stupid question- I've never looked at the grub
source code before.

Thanks

Rob
