chown doesn't complete properly

[momeunier]

When using chown I can't get autocompletion to work.
If I type chown -R [tab]
it does chown -R off:
like off is the only user available... I do this as root so it should just prompt all the available users.
I often do chown -R ww[tab] and I got nothing...
However if I type www-data:[tab] then I get the group part without any problem

Duplicate of issue #1857, commit c4434d2 broke completion.

zstyle ':completion:*' users off

on line 48 of lib/completion.zsh should be removed.
