 1) Make the code readable (don't use short variable names such as `tx`,
 `w`, `tc`, `t`, `wc`, `c`, which have no meaning).
 2) Make the word count function more abstract so that it can be used
 elsewhere. So, it should only count the words in a given text, nothing
 else.
 3) Maybe move to `wp-includes`.
 4) The word count should update at the right times. At the moment it
 updates on `enter`, `delete` and `backspace`. It should at least be
 updated on `space` too. Consider things like cut and paste, and look at
 TinyMCE events that change the content.
 5) Exclude more patterns like known shortcodes and ellipsis (#27386,
 #27391).
 6) Add some good unit tests for all of this.
 7) Make sure it's as fast as it can be (e.g. don't needlessly manipulate
 the DOM).

 This could be a small improvement that makes people less annoyed with
 WordPress. :)

 More inspiration, although not ideal either:
 https://github.com/tinymce/tinymce/blob/master/js/tinymce/plugins/wordcount/plugin.js

 Depends on: #26620, #27386, #27391.
