[PATCH v3 0/7] diff stat calculation adjustments

I broke the patch series up into smaller patches. Hopefully this makes the intent of the changes easier to follow.

Zbigniew's tests were added as PATCH 1/7.

The order of the options->stat_graph_width test was reverted back to the original order as per Zbigniew's feedback. There remains an issue where name_width (or graph_width) could be set to a value greater than stat_name_width (or stat_graph_width). This patch doesn't address the issue -- v2 had a partial fix, but it resulted in other problems anyway.

Lucian Poston (6):
  Add output_prefix_length to diff_options
  Adjust stat width calculations to take --graph output into account
  t4052: Adjust --graph --stat output for prefixes
  t4052: Add tests to illustrate issues with restrictive COLUMNS
  Prevent graph_width of stat width from falling below min
  t4052: Adjust --stat output for minimum graph_width

Zbigniew Jędrzejewski-Szmek (1):
  t4052: test --stat output with --graph
