+ Warn if changes introduce whitespace errors. What are
+ considered whitespace errors is controlled by `core.whitespace`
+ configuration. By default, trailing whitespaces (including
+ lines that solely consist of whitespaces) and a space character
+ that is immediately followed by a tab character inside the
+ initial indent of the line are considered whitespace errors.
