Deprecate sticky_class function

[solarissmoke]

I was rummaging around post-template.php and found the sticky_class() function, which was meant to be used by themes like so:

<div class="post<?php sticky_class(); ?>" id="post-<?php the_ID(); ?>"> 

Of course now we have

<div <?php post_class(); ?> id="post-<?php the_ID(); ?>">

sticky_class() should be deprecated.

I'm not sure this is a great idea post_class only shows 'sticky' for the first page, while sticky_class will be applied to the sticky post on any page ( archives, categories, etc).

As far as I can tell they do not do the same thing.

Replying to wycks:

As far as I can tell they do not do the same thing.

Then post_class should be modified to do what sticky_class did for back compat. Point is we should be using post_class to deal with all post classes.

sticky_class() and post_class() were both introduced in 2.7. Based on [8637] and [8638] it looks like sticky_class() should have just died then.

+1 to a straight deprecation, with no changes to post_class().

In [21253]:

Deprecate sticky_class() in favor of post_class(). props solarissmoke, fixes #16675.
