+--no-add::
+       When applying a patch, ignore additions made by the
+       patch.  This can be used to extract common part between
+       two files by first running `diff` on them and applying
+       the result with this option, which would apply the
+       deletion part but not addition part.

+--allow-binary-replacement::
+       When applying a patch, which is a git-enhanced patch
+       that was prepared to record the pre- and post-image object
+       name in full, and the path being patched exactly matches
+       the object the patch applies to (i.e. "index" line's
+       pre-image object name is what is in the working tree),
+       and the post-image object is available in the object
+       database, use the post-image object as the patch
+       result.  This allows binary files to be patched in a
+       very limited way.
+
+--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
+       behavior:
++
+* `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.
