I just put this down to a quirk/bug (it's there in 8.2-9) but it sounds like it's not an issue for anyone else. I'm defining them in rc.conf:

Sorry - should have said I'd obfuscated the IP addresses and hostnames 
(it's not really "one.mydomain.com" ;-) ) Unfortunately I forgot to 
obfuscate the jail name as fully as I thought in the startup lines. It 
should have read jail_one_rootdir &c.

As I said, it's been working happily for years on lots of different 
installations and they're all configured the same. The only weirdness is 
that the jail name appears in the table as it's number.

Regards, Frank.
