 override `ignore`.

  * Tracking issue: [#64245](https://github.com/rust-lang/rust/issues/64245)
 
 Using these options looks like this:
 
 ```bash
-$ rustdoc src/lib.rs -Z unstable-options --runtool runner --runtool-arg --do-thing --runtool-arg --do-other-thing
+$ rustdoc src/lib.rs -Z unstable-options --test-runtool runner --test-runtool-arg --do-thing --test-runtool-arg --do-other-thing
 ```
 
 These options can be used to run the doctest under a program, and also pass arguments to
 that program. For example, if you want to run your doctests under valgrind you might run
 
 ```bash
-$ rustdoc src/lib.rs -Z unstable-options --runtool valgrind
+$ rustdoc src/lib.rs -Z unstable-options --test-runtool valgrind
 ```
 
 Another use case would be to run a test inside an emulator, or through a Virtual Machine.
