Hello Erik,

thanks for the (general) reply. It seems you do not like backslashes as much as I do. I've cleared the string up with \v and could finally found my mistake.
It turned out that the above regex (regardless to \v) was not broken at all. (The greediness just of a branch prevent the matching of ^$.)
