[Patch] Use absolute offset for embedding area in grub-setup (i386-pc)

[Grégoire Sutre]

Hi,

The attached patch uses grub_partition_get_start (p) instead of p->start
in grub-setup's iteration over partitions.  While we are at it, also
use grub_partition_get_len (p) instead of p->len.

An alternative would be to assume that partitions are properly nested,
and therefore iterate only over the top-level ones (i.e. those with
p->parent == NULL).  In that case, we could equivalently use p->start.


In the check for non-empty embedding area, the patch uses <= instead of
== (as we may have embed_region.start == 1 && embed_region.end == 0).

Comments?
