bug#22599: Feature Request: Add ability to pass blank/empty partition name when using --script

[Dev User]

When using interactive mode it is possible to specify an empty partition name 
for the mkpart command.   However, when using the --script option an error 
occurs because it doesn't handle an empty name.

This results in an error:
                sudo parted --script /dev/xvdf mklabel gpt mkpart '' 'ext2' 
'0%' '100%' print all


This works, but you have to specify a name:
                sudo parted --script /dev/xvdf mklabel gpt mkpart MyPartName 
'ext2' '0%' '100%' print all


Ideally I could just specify:
                sudo parted --script /dev/xvdf mklabel gpt mkpart 'ext2' '0%' 
'100%' print all
and parted would parse the parameters correctly but requiring a  '-'  or '--'  
(or whatever)  would work too.
