Subject: sfdisk 2.20.1 --no-reread do BLKRRPART

Hi,
When creating partitions on a destination that is not a block device,
sfdisk do a BLKRRPART ioctl even when --no-reread option is used, but
looking at documentation --no-reread only apply to the beginning
process.
Would it be fine to extend that to the complete process ?
