Subject: [PATCH v2] graph: fix coloring around octopus merges
When drawing the graph of an octopus merge, we draw a horizontal line
from parents 3 and above into the asterisk representing the commit. The
sections of this line should be colored to match the graph lines coming
in from above.
However, if the commit is not in the left-most column we do not take
into account the columns to the left of the commit when calculating
these colors. Fix this by adding the appropriate offset to the column
index used for calculating the color.

It took me a minute to spot the problem when I tested this, but you're
right that there is a bug and I agree that the patch below is the right
fix.
Perhaps a better commit message will help others looking at this, maybe
something like this?

The section below the "---" does not become part of the commit message,
when the patch is added to Git, but is used for notes that might help

[PATCH] graph: Fix log's graph's colors when merging branches.

Subject: [PATCH] graph: Fix log's graph's colors when merging branches.
The log's graph's colors were off sometimes when merging several
branches. For example in the graph depicted below, the '-.' part
following the asterisk was colored with incorrect colors. This was
caused by the fact that the leftmost branches, not part of the merge,
were not taken into account when calculating the column numbers
(colors).
