Bug in mkdir 5.0

[Pascal Gwosdek]

Hi,

it seems I found a little bug in mkdir 5.0.

Let's say I have some files named "Hello WorldAnything", where 
'Anything' is the rest of the corresponding file names.
I now want to sort them and thus create a new directory called "Hello 
World". I want to save time and use the Tab-key to complete the line.

I type

mkdir Hello\ W<Tab-key>

and the line is completed to

mkdir Hello World

without backslash!
The result are two new directories named "Hello" and "World".
I'm not sure if this is a bug in mkdir (coreutils) or directly in the 
kernel (in this case I wonder why it's ok with other commands, such as 
'rm' or 'cp'), but it's really annoying.

I hope my description helps. :-)
