<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Coding Standards: Use more meaningful variables names in some Ajax functions.
This renames `$tax` to `$taxonomy_object` and `$s` to `$search` for clarity. The latter is only renamed when used as an internal variable and not referring to the `$s` global.
The list of affected functions:
* `wp_ajax_ajax_tag_search()`
* `wp_ajax_add_link_category`
* `wp_ajax_add_tag()`
* `wp_ajax_get_tagcloud()`
* `wp_ajax_inline_save_tax()`
* `wp_ajax_find_posts()`
