[PATCH 0/3] Make support for multi-value configuration options more consistent

This series adds support for optional placing of additional whitespace characters around the commas in the multi-value, comma-separated values for the "diff.dirstat" and "diff.wsErrorHighlight" configuration options, and the "--dirstat" and "--ws-error-highlight" command-line options.

This makes the way multi-(sub)value configuration options can be specified more consistent, because exactly the same additional whitespace characters are already allowed for some of the configuration options. It may also make the configuration files more readable to some users.

Dragan Simic (3):
  diff: support additional whitespace in diff.{dirstat,wsErrorHighlight}
  t4015: whitespace in diff.wsErrorHighlight and --ws-error-highlight
  t4047: whitespace in diff.dirstat and --dirstat
