From: Josef Kufner <josef@xxxxxxxxx>
Pass graph width to pretty formatting, to make N in '%>|(N)'
include columns consumed by graph rendered when --graph option
is in use.
For example, in the output of
git log --all --graph --pretty='format: [%>|(20)%h] %ar%d'
this change will make all commit hashes align at 20th column from
the edge of the terminal, not from the edge of the graph.
