A match that contains a newline is silently truncated(!) at the
newline.
+
+For example, `--word-diff-regex=.` will treat each character as a word
+and, correspondingly, show differences character by character.
++
The regex can also be set via a diff driver or configuration option, see
linkgit:gitattributes[1] or linkgit:git-config[1]. Giving it explicitly
overrides any diff driver or configuration setting. Diff drivers
initial indent of the line are considered whitespace errors.
Exits with non-zero status if problems are found. Not compatible
with --exit-code.
+
+--ws-error-highlight=<kind>::
+ Highlight whitespace errors on lines specified by <kind>
+ in the color specified by `color.diff.whitespace`. <kind>
+ is a comma separated list of `old`, `new`, `context`. When
+ this option is not given, only whitespace errors in `new`
+ lines are highlighted. E.g. `--ws-error-highlight=new,old`
+ highlights whitespace errors on both deleted and added lines.
+ `all` can be used as a short-hand for `old,new,context`.
