Anyway, this looks okay to me; do you have a problem if I merge this via the audit/next branch or were you hoping to have this go in through a different tree? -- paul-moore.com

Merging it through your tree is probably best, Andrew can either pick the ones that nobody else took, or I can resend the rest. Arnd

Easy enough, merged to audit/next, thanks.
