+       whitespace errors.  What are considered whitespace errors is
+       controlled by `core.whitespace` configuration.  By default,
+       trailing whitespaces (including lines that solely consist of

+       by a tab character inside the initial indent of the line are

 * `nowarn` turns off the trailing whitespace warning.
 * `warn` outputs warnings for a few such errors, but applies the

+  patch as-is (default).
+* `fix` outputs warnings for a few such errors, and applies the
+  patch after fixing them (`strip` is a synonym --- the tool
+  used to consider only trailing whitespaces as errors, and the
+  fix involved 'stripping' them, but modern gits do more).
 * `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.
