Looks like the equivalent of commit
10e4bd3780050e75b72aac5d85c31816419bb17d for catan was not applied to
catanf. It should be an easy fix. I'll look at it.

BTW your mail contained an empty plaintext part and the actual message
was buried in the html version. I was able to dig it out to reply, but
try to send text-only or at least with a matching text part since many
readers probably can't see your email and the archive probably missed
the body.
