bug#42496: Option not working in scripting mode.

[Sachiel2008 via Bug reports for the GNU Parted disk partition editor]

Dear GNU

I found the following command op the internet:

> root@localhost # parted -a optimal /dev/sda
>
> (parted) unit mib
>
> (parted) mkpart primary 515 -1

However, when I try to turn it into a part of a script like this:

> root@localhost # parted --script /dev/sda mkpart primary 515 -1

Greetings, Sachiel2008
