Allow to use order_by in addition to orderby

The above link and the same for wp_list_categories suggests that you can order categories by count. In practice it seems to ignore the parameter. It doesn't seem to work with a few other parameters either -- the only things that seem to work are ID, name, and slug, but these might merely be incidental to the fact that I created my test categories in alphabetical order.

Oh, bummer, nevermind -- a silly typo: I used order_by instead of orderby...

So, rephrasing this as an enhancement request: be more forgiving and allow to use order_by as well as orderby.

We're not great on consistency in general, but we use "orderby" exclusively in core.

The only places where "order_by" is found are:

• As a local variable in class-wp-ms-sites-list-table.php (but it represents $_GET['orderby'])
• As dead code in edit-link-form.php that was removed in [23445] but re-added in [23554] (and now about to be removed again)

Good to see you again, Denis.

Replying to Denis-de-Bernardy:

Adding order_by as an alias for orderby just in get_categories() would be inconsistent with other functions that accept orderby.

Doing that for all the functions still doesn't seem like a good idea.

Closing as invalid - this doesn't seem like something we should be doing.
