This variable has a very confusing name given that context in which this variable is used (content filtering, editing, article_), the word "text" should refer to the page content, but alas, this variable refers to the page title.
Especially given the existence of `wikitext`, `Revision::getText`, `text` database table etc,.
So why is this variable named that way? It's originally named that way to distinguish itself from `article_prefixedtext`, which is named after the MediaWiki PHP code method `Title::getPrefixedText` at which point the word "title" unfortunately got lost, despite being the most important word in that signature.
`Title::getPrefixedText` itself is named that way to distinguish itself from `Title::getText` (which is the page name without the namespace prefix), and `Title::getDBKey/Title::getPrefixedDBKey`, which is a variant of the page title where spaces are replaced with underscores instead.
So all this where the word "text" means (textual form, as opposed to database form).
Proposing to rename these to `page_title` and `page_prefixedtitle`.

We should consider renaming the ones used by `move` as well - and for all, we'll keep the old ones as aliases for back-compat.
