more parted bugs

[Ethan Benson]

Hi, 

just found a nasty bug in parted, it creates too many Apple_Free
partitions, actually this could be a more generic problem that its
currently impossible to create perfectly contigious partitions with
parted.  (you need my mkpart primary ext2 - 50 trick for that) 

this is bad because when i created 9 partitions i ended up with 17,
which overflows the limits of scsi so the kernel assigned the last two
to /dev/sdb and /dev/sdb1 !

here is the exact same partition table created by mac-fdisk:

Command (? for help):

same number of partitions (except for the one between map and
bootstrap, thats because your partition table is one block longer...)

so i guess making perfectly contigious partition tables is more
important then just being a pedant afterall ;-)
