It would make sense to add them, I'd love to promise to do that, but
can only promise instead to try.

Can you open a bug on bugs.koha-community.org (or update one if it is
already there)?

Hi Chris,

I should have looked, there is already a bug (http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=6709) from Frèdéric,

last comment from Katrin on 2012-02-13, same problem.

Thanks
