https://code.edge.launchpad.net/~twisted-dev/twisted/trunk reports wrong branch format

According to bzr, the mirror is also in format 7:
$ bzr info nosmart+lp:~twisted-dev/twisted/trunk -v
Repository branch (format: 1.14-rich-root or 1.9-rich-root)

Interesting. The web UI https://code.edge.launchpad.net/~twisted-dev/twisted/trunk page still claims Branch format 6.
