dumpon "AUTO" not implemented?

[Ivan Voras]

The man page on rc.conf states that "AUTO" can be given to dumpon 
variable and it will save the coredump to first suitable swap device. I 
tried this today and it doesn't work - during boot, there's a line like 
"dumpon: 'AUTO' is not a valid device". By quick grepping in /etc/rc.d 
it seems that 'AUTO' is not implemented.

So, this should probably be implemented or removed from man page :)

(this is 5.4-PRERELEASE, apologies if it's fixed already)
