[PATCH 1/3] pretty: Pass graph width to pretty formatting for use in '%>|(N)'

[Josef Kufner]

Pass graph width to pretty formatting, so N in '%>|(N)' includes columns
consumed by graph rendered when --graph option is in use.

Example:
  git log --all --graph --pretty='format: [%>|(20)%h] %ar%d'

  All commit hashes should be aligned at 20th column from edge of the
  terminal, not from the edge of the graph.
