Omit code output going forward

In a couple of issues now, we've run into an impass because it's unclear if we still need to include the output of code samples in manual pages. There is the new in-page runner, which is guaranteed to give "correct" results (or error if it's showing a feature that is incompatible). I'd like to see us formally and explicitly decide on a policy here. And I will start by proposing that in most cases, we DO NOT need to include manually-created output, as the in-page runner is superior and takes less work for doc writers. The only exception is where the runner doesn't support the code being shown for whatever reason. (Like, it requires a file system, or some non-loaded extension, etc.) In those cases, the traditional approach with a manual output block still makes sense. But that's a minority case now. -- Larry Garfield larry@garfieldtech.com
