Auto-completion seems broken with umount command

Bug Description

I'm using Xubuntu with the devel version. I've seen this bug with Ubuntu also, in the daily version.

The auto-completion of the command 'umount' seems broken.

I have an usb key called "Xubuntu 16.10 amd64". I verify that with the command lsblk.

Then, I type 'umount /media' then I press 'tab' to have the autocompletion. With 16.04, the autocompletion completes correctly with backslash : "/media/nairwolf/\ Xubuntu\ amd64"

But, now, with Yakkety, the autocompletion stops before the first space.

There is a screenshot to explain what I have :

Don't forget that I'm typing only "umount /media", and then, I press tab to have the autocompletion. And this picture is the result of the auto-completion.

I'm unable to reproduce that with other basic command like "ls", "cd" or "rm". That means if I'm typing "ls /media", then "TAB" it will be completed correctly.

Using tab to complete the Ubuntu directory here I got the following:

 $ ls /media/bdmurray
Ubuntu 16.04 LTS amd64
[ 3:39PM 12880 ] [ bdmurray@impulse:~/source-trees/update-notifier ]
 $ umount /media/bdmurray/Ubuntu$'\001'6.04\ LTS\ amd64
umount: /media/bdmurray/Ubuntu6.04 LTS amd64: No such file or directory

That was with zsh though, I switched to bash and it was fine. What shell are you using?

Did you say it works for you with Bash ?
