Hi Nicolas,

Thanks for your patch.

You should Cc Paul Mackerras <[email-masked]> on gitk patches.

You don't need these headers, they'll be taken from the email.  You only
need to put them if they don't agree (e.g., you are sending someone
else's patch).

Can you describe your patch in more detail, and spin a commit message
from it?  My first reaction to "Add a scrollbar for commit history in
gitk" is "there *is* a scrollbar".

The code hints that the scrollbar may be horizontal?  Is this worth the
vertical space it spends?  Should it be optional?  The commit message
should address these questions.

You should eventually base your patch against the gitk.git repository,
which does not have the toplevel gitk-git/ prefix.
