Plugin FAQ anchor links get broken when used in a forum post

[johnbillion]

I've noticed that when I copy a URL to a plugin FAQ and paste it in a support forum reply, it gets broken. The copied link is correct and works, it just gets mangled when saved in the forum reply.

Latest example here: ​https://wordpress.org/support/topic/tracking-user-switching/#post-13898580

This is an affected link, seems to work okay in Trac: ​https://wordpress.org/plugins/user-switching/#%0Aare%20any%20plugin%20actions%20called%20when%20a%20user%20switches%20account%3F%0A

The forum is stripping the %0A encoded character at the beginning and end of the fragment in the URL. %0A is the encoded newline character. I think the forum is correct, here, and the fix should be applied to the plugin pages to trim() the FAQ titles before encoding/escaping the URL.

In 10573:

Plugin Directory: When generating FAQ anchors, don't include trailing whitespace as part of the ID.

This also updates the format of pre-defined ID's to match the format used today, as the ID's were previously being stripped out by kses, there's no real change here.

The Decode/Encode and trimming works around the various different anchor formats used.

Fixes #5572.

Plugin Directory: Bump JS cache after [10573].

In 10606:

Plugin Directory: Stop adding a # when generating FAQ IDs in JavaScript.

This keeps the behavior consistent between PHP and JS.

See #5572.
