pretty: pass graph width to pretty formatting for use in '%>|(N)'

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.
