1 If a comment contains a WikiLink, for a page that doesn't exist, and the
2 user clicks on the edit link, and creates the page, it will itself be saved
3 as a comment, with "._comment" extension.
5 This is very surprising and wrong behavior. The page editor tries to
6 preserve the linking page's format type, but it shouldn't do so if the page
7 is an internal page. --[[Joey]]
