Subject: [PATCH] Don't tab-complete namespaced commands if send-namespaced is
 false

Tab-complete packet is supposed to tab-complete args for commands, but
it also can suggest commands like in version 1.12.2 or lower.

This patch prevents server from sending namespaced commands when player
requests tab-complete only commands.
