If an administrator deletes an article with versions he gets a hint: "Be
carful, there are versions".
In many cases it would be helpful if he gets the infomation HOW MANY versions
A user creates a nonsense article with contents "aabbccdd". Another user edits
this article to vote for deletion. Now this article has 2 versions.
If I want to delete this article and I get the info "2 versions", I can hit
the "ok-button". If there are more than 2 versions I must look into the history
because a previous version may have excellent contents.
Without the info about the number of versions I always must chck the history.
