-'APIEditBeforeSave': DEPRECATED since 1.28! Use EditFilterMergedContent instead.
-Before saving a page with api.php?action=edit, after
-processing request parameters. Return false to let the request fail, returning
-an error message or an <edit result="Failure"> tag if $resultArr was filled.
-Unlike for example 'EditFilterMergedContent' this also being run on undo.
-Since MediaWiki 1.25, 'EditFilterMergedContent' can also return error details
-for the API and it's recommended to use it instead of this hook.
-$editPage: the EditPage object
-$text: the text passed to the API. Note that this includes only the single
- section for section edit, and is not necessarily the final text in case of
- automatically resolved edit conflicts.
-&$resultArr: data in this array will be added to the API result
