Twenty Fourteen: Replaces ellipses with ellipses and a Continue reading link.

[davidakennedy]

To help meet accessibility-ready requirements, we need to make clean automatically-generated excepts. We should replace the ellipses (appended to automatically generated excerpts) with a Continue reading link.

The theme already carries the accessibility-ready tag but this was missed previously.

This would mirror what we already do in the content.php and other content areas, and is catching another use-case:

<?php
    /* translators: %s: Name of current post */
    the_content( sprintf(
        esc_html__( 'Continue reading %s', 'twentyfifteen' ),
            the_title( '<span class="screen-reader-text">', '</span>', false )
        ) );
?>

We could add it in the template-tags.php file and follow this example: ​http://www.fklein.info/read-more-link-excerpts/

Note: I neglected to mention that the patch also modifies the content template parts to include a visually hidden post title for screen reader users.

Removes leading space; concatenates ellipses with spaces and link.

In 30389:

Twenty Fourteen: replace ellipses appended to automatically generated excerpts with both ellipses and a "Continue Reading" link to meet accessibility-ready requirements.

Props davidakennedy, lancewillett. Fixes #30176.
