$ redis-cli -v
redis-cli 3.1.103
$ echo -e multi\\ninfo | redis-cli
OK
QUEUED$ echo -e multi\\nget s | redis-cli
OK
QUEUED
$
Also the same when typing multi [enter] info [enter] in redis-cli prompt.
Redis itself sends +QUEUED\r\n over the wire but redis-cli seems to strip line break, and for INFO only.

There are a number of cases in which redis-cli automatically enables raw output mode, and it would seem that this is one of them. One possibility would be disabling raw output while MULTI is queuing commands, though I'm not sure if this might have side effects in some scenario.
