I had a -> Option<PathBuf> fn, which I wanted to change to Result<PathBuf, _>, but despite advertising to do so, the assist did not
change the result type to Result<PathBuf, _> but instead just wrapped it in a Result: <Result<Option<PathBuf>, _>.
I changed the assist description to "Wrap return type in Result" to clarify that the assist only wraps the preexisting type and does
not do any deep Option-to-Result refactoring.
