I noticed [my answer](https://askubuntu.com/revisions/1020934/3) to a question was subsequently [revised](https://askubuntu.com/revisions/1020934/4) for no other reason than using markdown per syntax.  It seems to me pre-numbering items to define a sequence is syntactically correct, but less flexible or clear (in a diff) if edited.

However, it led me to wonder what is the preferred formatting of an ordered list using markdown?  I can't find a style guide for a preference for numbered lists: [A: Style guide for questions and answers](https://meta.askubuntu.com/questions/89/style-guide-for-questions-and-answers/103?s=3|8.0100#103).
