Subject: [PATCH] libparted: make sure not to treat percentages as exact

If 1% of the drive size worked out ot be an even power of
two, it would trigger the exact placement.  Add an exception
for the percent units.

Petr Uzel <puzel@suse.cz>:
Also avoid this logic when the unit is specified as cylinders.
