[Bug 1622987] [NEW] Auto-completion seems broken with umount command

[Nairwolf]

Public bug reported:

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.
