When updating an existing taxonomy term that shares its `term_id` with
another term, we generate a new row in `wp_terms` and associate the updated
term_taxonomy_id with the new term. This separates the terms, such that
updating the name of one term does not change the name of any others.
In cases where a plugin or theme stores term IDs in the database, term splitting
can cause backward compatibility issues. The current changeset introduces
two utilities to aid developers with the transition. The `'split_shared_term'`
action fires when the split takes place, and should be used to catch changes in
term_id. In cases where `'split_shared_term'` cannot be used, the
`wp_get_split_term()` function gives developers access to data about terms
that have previously been split. Documentation for these functions, with
examples, can be found in the Plugin Developer Handbook. WordPress itself
stores term IDs in this way in two places; `_wp_check_split_default_terms()`
and `_wp_check_split_terms_in_menus()` are hooked to `'split_shared_term'` to
perform the necessary cleanup.
See [30241] for a previous attempt at the split. It was reverted in [30585]
for 4.1.0.

To better understand screen reader text, check out https://make.wordpress.org/accessibility/2015/02/09/hiding-text-for-screen-readers-with-wordpress-core/
Screen Reader text improves the user experience for screen reader users. It provides additional context for links, document forms and other pieces of a page that may exist visually, but are lost when looking only at the html of a site. This does change the output of comments_popup_link if you don't pass in values for $zero, $one, $more or $none. Theme authors can and should style <code>.screen-reader-text</code> in ways that are recommended in the above article to hide it visually.

It's possible to have an empty `tax_query` and `is_tax=true` when the initial
query contains a taxonomy var (and is processed as such during
`WP_Query::parse_query()`) but the taxonomy var is unset during a 'parse_query'
callback. While this kind of behavior is not necessarily something we need to
support, we should continue to avoid PHP notices in such cases, as we did prior
to WP 4.1.

When editing a post, non-hierarchical taxonomy terms are sent as the
comma-separated list entered into the tax_input metabox. Passing these
values directly to `wp_update_post()` meant that they were interpreted as
term slugs rather than term names, causing mismatches when a typed string
matched the slug of one term and the name of a different term. We fix the
problem by preprocessing tax_input data sent from post.php, converting it to
unambiguous term_ids before saving.
