In CVS:
If an article with less than 500 characters is to be deleted, at most the first 150 characters are automatically suggested as a deletion reason. This should automate the frequent practice of pasting the text of nonsense articles into the deletion reason.
If an article with a history is to be deleted, a warning is inserted, linking to the article history (so as to avoid accidentally deleting a vandalized page with a valid history).
If a blanked article with a history is to be deleted, and the next earlier revision contains less than 500 characters, at most the first 150 characters are automatically suggested as a deletion reason. Nonsense pages are often blanked, just checking the current revision for nonsense is not good enough.
New texts in Language.php for this feature: - excontent, exblank, exbeforeblank, historywarning
