Oh, I had a deeper look at the "-e" section of the man page where this
statement is clear enough.Thanks.

No, not a case in the real world. I was just playing around with jails
on a server and tried to get the ip4 field of a specific one to make
sure it was set to 'inherit'.
P.-S.:
However, I had time to write a short patch (attached to the email) to
make it work with a jail list as arguments.
( and that do not change the header file anymore )
This one also add a dedicated line for the "-e" command and fix few
typos in the usage() output.
// To improve the lookup in the nested loop, I first called "TAILQ
REMOVE" on jailnames when found but this would produce errors if the
user add more than once the same name in the list .//
