Editor: Word count should exclude shortcodes

[bassgang]

On the post edit screen the Word count includes shortcodes, but they should not be considered as normal words and so not increase the count.

Steps to reproduce:

• Add a new post.
• Add a gallery to the newly created post.
• Save the post.
• Reload the page.
• Check "Word count" under the content textarea, it says "2".

As pointed out by azaozz: "to make that work properly we need to output an array of shortcode "names", then exclude them in the word count".

Who can provide guidance to show which is the most likely way to get this information available in JS?

add qunit test for word count

[adamsilverstein]

27386.2.patch​ adds a (QUnit) unit test to verify that the word count feature correctly skips shortcodes when counting words. The test fails without the patch in /wp-admin/js/word-count.js and passes once the file is patched. Note: the test needs to be asynchronous because the word count function includes a brief delay and would otherwise complete after the assertion ran.
