Allow additional whitespace characters to be placed around the commas
in the multi-(sub)value, comma-separated values for the "diff.dirstat" and
"diff.wsErrorHighlight" configuration options. This makes the way multi-value
configuration options can be specified more consistent, because exactly the
same additional whitespace characters are already allowed for some of the
configuration options, including "core.whitespace", "log.graphColors" and
"color.blame.highlightRecent".
Besides improving the consistency of the configuration syntax, being able
to include additional whitespace characters into the values of a couple more
of the comma-separated configuration values may also make the configuration
files more readable to some users.
This optional support for the additional whitespace around the commas also
extends to the equivalent comma-separated values for the "--dirstat" and
"--ws-error-highlight" command-line options.
