[PATCH] Documentation: Simplify git-rev-parse's example

[Pieter de Bie <pdebie@ai.rug.nl>]

This example was overly complex and therefore confusing.
The commits have been renamed to start the oldest commit with "A"
and working up from there. Also, this removes some commits so the graph
is simpler. Finally the graph has been reversed in direction to make it
more like gitk.

This was created after some discussion in #git about how this was confusing.
The consesus was that this example is better.
