Hi Mickael,
Cool. Will take a proper look at this later. Some of your fixes
overlap with changes that we already have pending but aren't committed
yet. But there are some good fixes in here.
There is a small problem though. Your e-mail client seems to replace
tabs with spaces, which means your patches don't apply. You may be
able to fix that in your e-mail client. As a last resort you could
include your diffs *both* inline and as an attachment.
Cheers,
Mark
