Articles with already flagged revisions have several pointers to flagging process within the Page History page, as well as when seeing a diff there.
Articles with no revisions are now a big exception: the only way to initially review is to find the "hidden" field at the very bottom of the article itself (for me it's so well hidden I wasn't able to find it myself, probably because I always look for everything for editors at the top), and there is no review link on Page History page, nor in the diffs.
This is inconsistent with the rest of the flaggedrev UI IMHO.
