Save and Continue Editing with blank title/body gets to bad state

[jhodgdon]

Log into your WordPress admin panel.

Click "Write" to create a new post. It does not matter if you are using the rich text editor or plain editor.

Click "Save and Continue Editing", without entering a title or body for your post. (For instance, someone might check a category or enter some other metadata and click Save and Continue Editing; but to reproduce this bug, you can just immediately click Save and Continue Editing)

You will be redirected to a page with the following URL, relative to your blog dir:

wp-admin/post.php?action=edit&post=0

You will see a blank post editing screen, except that any edits you might have made in post metadata, categories, etc., and your usual post defaults (comment/trackback preferences), are all lost.

I think the correct behavior should be (assuming we don't want to save a post with no title/content) to open up the default post again (as if user just clicked on Write), and to warn the user that the post was empty and not saved, up at the top of the screen in one of those handy-dandy fading message bars.

I originally found this bug on a site running 2.1.x. I then verified it is still there in 2.2, and also in [5655], on a fresh install from scratch with no plugins running.

Patches to wp-admin/post.php and wp-admin/post-new.php, which make it so Save and Continue Editing on a blank post goes to new Write screen with warning message at top of screen

[jhodgdon]

Note that patch above also causes the same (I think desirable) behavior to happen if you go to the Write page and click Save rather than Save and Continue Editing.

This was duped by #4855 (after the 0 post id had been killed my another commit)
