795733c59e Add a large comment about disk geometries. 
Rename (with #defines) the variables use for aligning partitions to
separate them from the bios geometry.
All in advance of allowing other partition alignments (eg 2048 sectors).

1735ad7d34 Update -u usage to follow changes in fdisk.c rev 1.125: 
>> Allow MB, GB and CYL (not just M, G and C) and lower case.
>> Don't output a splurious 'd' before "cyl".
>> Fixes PR/37414.

XXX "NNcy" is also allowed?

fcf4b7e0c1 Remove fdisk/mbr for macppc which was blindly pulled from OpenBSD. 
It just fakes MBR partition map which contains 1MB FAT16B partition
and ~1GB OpenBSD partition, and we can always create necessary
MBR partitions for OpenFirmware by the fdisk(8) command itself.
