Subject: [PATCH 11/12] parted: Preserve resizepart End when prompted for busy
 partition

Resizing busy partitions is allowed, but the user is prompted, which
erases the cmdline. It is annoying to have to re-end the ending location
after answering Yes. This saves the word and pushes it back onto the
cmdline after the user agrees to resize the busy partition.
