# jail -c persist osrelease="$(echo major=1; echo minor=0)"
# jls
JID IP Address Hostname Path
145 /
# jls osrelease jid
major=1
minor=0 145

the manpage clearly states:

Each jail is represented by one row which contains space-separated values of the listed parameter

Either we should amend the manpage, or swap newlines for spaces consistently on all parameters.

It seems that a trailing newline is removed, so perhaps for consistency we should replace all newlines with space when this single-line output is used.
