+--whitespace=<option>::
+       When applying a patch, detect a new or modified line
+       that ends with trailing whitespaces (this includes a
+       line that solely consists of whitespaces).  By default,
+       the command outputs warning messages and applies the
+       patch.
+       When `git-apply` is used for statistics and not applying a
+       patch, it defaults to `nowarn`.
+       You can use different `<option>` to control this
+       behaviour:
++
+* `nowarn` turns off the trailing whitespace warning.
+* `warn` outputs warnings for a few such errors, but applies the
+  patch (default).
+* `error` outputs warnings for a few such errors, and refuses
+  to apply the patch.
+* `error-all` is similar to `error` but shows all errors.
+* `strip` outputs warnings for a few such errors, strips out the
+  trailing whitespaces and applies the patch.
+
+
+Configuration
+-------------
+
+apply.whitespace::
+       When no `--whitespace` flag is given from the command
+       line, this configuration item is used as the default.
