Bug#913001: live-wrapper: Handle firmware list more robustly by using proper whitespace split

[Witold Baryluk <witold.baryluk@gmail.com>]

Package: live-wrapper
Version: 0.7
Severity: normal
Tags: patch

Hi,

Patch against current master branch in attachement.

"
    Fix splitting of firmare package names
    
    split(' ') literally splits on a single space:
    
    'firmware-a  firmware-b'.split(' ') == ['firmware-a', '', 'firmware-b']
    
    Use split() that automatically removes empty elements (equivelent to
    strip + remove if empty), and splits on tabs and newlines.
    
    This makes human provided arguments be handled more robustly.
"

Thanks.
