graph: add --[no-]graph-indent and log.graphIndent Some users may prefer to not have graph indentation. Add "log.graphIndent" config variable to graph_read_config() to read the default preference. By default is graph indentation is true. Add --graph-indent and --no-graph-indent options to overwrite the default preference.
