- Document the HISTORY of fdisk based on the original post to comp.unix.bsd by

Julian Elischer [1] and the Mach 2.5 Installation notes [2].
I was unable to pin point the exact version of Mach the fdisk utility appeared
as I didn't find documentation older than version 2.5 & no source code or repo
history. fdisk utility appears as a separate utility[3] in v2.5. Due to this,
I've avoided stating the exact version fdisk first appeared in Mach.
- Make correction pointed by textproc/igor
- Bump date
