This patch did require a rebase, but I manage to resolve the conflict
while applying the patch on my next track. Please have a look at the
result. Thanks!
Also, I took the liberty of removing the information about that this
is a v2 patch from the commit message. Future wise, please don't
include that in the actual commit msg, but keep it as "patch
information".
Kind regards
