Merge branch 'nd/graph-width-padded'
"log --graph --format=" learned that "%>|(N)" specifies the width relative to the terminal's left edge, not relative to the area to draw text that is to the right of the ancestry-graph section. It also now accepts negative N that means the column limit is relative to the right border. * nd/graph-width-padded: pretty.c: support <direction>|(<negative number>) forms pretty: pass graph width to pretty formatting for use in '%>|(N)'
