+--whitespace=<option>::
+       When applying a patch, detect a new or modified line
+       that ends with trailing whitespaces (this includes a

+       the command outputs warning messages and applies the

+* `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.
