Comments don't show in non-post edit screen meta box

[duck_]

Add some comments to a page and enable the Comments meta box on the page edit screen.

Expected: List of comments shown in the meta box.

Actual: No comments list. Just the "Add Comment" button.

This happens for all non-post content types.

In 3.3 the comments were not listed either, but a "Show Comments" link was available to fetch the list. Its disappearance was caused by [20164] which set the "Show Comments" link to always have the .hidden class. The removal of this link also means that a page refresh is required when enabling the meta box for the first time instead of being able to load the comments with a click.

It's possible to get the comments list to be displayed by enabling the comments meta box on the Post screen too. The fix for this is to use get_current_screen() in post_comment_meta_box() instead of just 'post'.

20937.diff​ also moves the "Show Comments" link into the else branch so that it and "No comments yet" are not shown at the same time. If they are and a comment is added then clicking "Show Comments" does not remove the no comments message. This is the same as 3.3 behaviour which bailed early if $total <= 1.

Seems minor, since the comments list was never shown here. Can wait for 3.4.1.

duck_ is going to shrink this patch a bit (no need for $total to move). It is also possible that for trunk, we can convert this to get_comments(), which accepts a 'count' arg.

20937.2.diff​ for the 3.4 branch.

20937.trunk.diff​ for trunk switches the SQL query to use get_comments().
