The view-source URI scheme doesn't works in the text editor. (even when using "other" as a protocol, the href is simply discarded)

It's a standard and useful URI scheme, that can be used to point beginners and non-coder directly to the source of a web page (instead of giving them lengthy and browser specific instruction on how to view the source)
