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

[Dragan Simic <dsimic@manjaro.org>]

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
