It is, of course, referring to the one you are trying to create.  Its
end point is not aligned.  Of course, there isn't much point to the end
being aligned so maybe we should only be checking the start.

Hi folks,

parted 3.2-17 (Debian Unstable) doesn't tell which partition
is misaligned. Sample session:

Partition 6 is perfectly aligned (320 MiB), so the warning
is very misleading. How about a message like

Warning: Partition 1 is not properly aligned for best performance.

Harri
