Subject: small patch for poudriere jail

Dear Baptiste,

first of all, Happy New Year, and have a very nice holidays!

I wish to propose small patch for poudriere list command, allowing automating 
of jail rebuild in a form like

apply 'poudriere jail -u -j' `poudriere jail -l -q -n`

Here is sample output

root at hamster:/usr/ports# poudriere jail -l -n -q
92amd64
9i386
9amd64
91amd64
root at hamster:/usr/ports# poudriere jail -l -q
92amd64              9.2-RELEASE-p2 r258725 amd64   svn     /usr/local/poudriere/jails/92amd64
9i386                9.2-STABLE r260136   i386    svn     /usr/local/poudriere/jails/9i386
9amd64               9.2-STABLE r260136   amd64   svn     /usr/local/poudriere/jails/9amd64
91amd64              9.1-RELEASE-p9 r258725 amd64   svn    /usr/local/poudriere/jails/91amd64

BTW, it seems 'n:' had been left in option string from earlier ages :)
