[PATCH v5 0/3] nd/log-graph-configurable-colors

v5 moves space trimming to color_parse_mem() from read_graph_colors_config, which is renamed to parse_graph... because the config reading is moved back to graph_init.

I think it looks better, but we may be pushing the limits of argv_array's abuse.

Nguyễn Thái Ngọc Duy (3):
  color.c: fix color_parse_mem() with value_len == 0
  color.c: trim leading spaces in color_parse_mem()
  log --graph: customize the graph lines with config log.graphColors
