What was the intention about "jail -e" in the first place ?

[David Marec]

The manpage and usage output doesn't match.

The manpage tells us that this option should be used alone on the 
command line, as any other command will be discarded.

The usage ouput does not mention the "-r" flag but "cmr" (with a typo).

Both suggest that the user can request information about one single 
jail, or all the jails using a wildcard or no other argument.

Well, looking at the code, it sounds that the only way to make it work 
is to use it alone on the command line, and their is no way get 
information about a single jail.

Attached is a short patch to get information about one single jail or 
all jails (wildcards or empty).


But,how was "jail -e" intending to be used, actually ?
