 In [changeset:"50011" 50011]:
 {{{
 #!CommitTicketReference repository="" revision="50011"
 Export: Create an export-specific filter for post titles.

 Since WordPress 2.5 and 2.6, `post_content` and `post_excerpt` have both
 had export-specific filters: `the_content_export`, and
 `the_excerpt_export`, respectively. `post_title`, however, has used
 `the_title_rss`, which behaves differently in two important ways:

 - It strips HTML tags from the string.
 - It HTML-encodes the title string.

 These behaviours are not ideal for exports, since it changes the post
 title, resulting in data loss in export files, and incorrect post
 duplicate matching on import. This changes replaces the usage of
 `the_title_rss` with a new filter, `the_title_export`. The new filter is
 intended to be used in the same as `the_content_export` and
 `the_excerpt_export`.

 Props jmdodd, audrasjb.
 Fixes #52250.
