 If I want to show an excerpt of a protected post, then I have to search
 the output of get_the_excerpt for a string like "There is no excerpt
 because this is a protected post." and replace this string by the actual
 excerpt.
 In a multilanguage environment this creates a source of possible errors.
 I would like to see that the filter "get_the_excerpt" is also applied to
 the "There is no excerpt ..." message.

 Code in the function get_the_excerpt could look like this:

 {{{#!php
 <?php
 function get_the_excerpt( $deprecated = '' ) {
         if ( !empty( $deprecated ) )
                 _deprecated_argument( __FUNCTION__, '2.3' );

         $post = get_post();
         if ( empty( $post ) ) {
                 return '';
         }
         $excerpt = '';
 // emanaku new
         if ( post_password_required() ) {
                 // return __( 'There is no excerpt because this is a
 protected post.' ); // emanaku replace with next line
                 $excerpt = __( 'There is no excerpt because this is a
 protected post.' ); // emanaku new
         }
         else {  $excerpt = $post->post_excerpt; };
 // emanaku new
         /**
          * Filter the retrieved post excerpt.
          *
          * @since 1.2.0
          *
          * @param string $post_excerpt The post excerpt.
          */
         // return apply_filters( 'get_the_excerpt', $post->post_excerpt );
 // emanaku replace with next line
         return apply_filters( 'get_the_excerpt', $excerpt ); // emanaku
 changed
 }
 }}}

 With this change a filter asking for protected content can hook into
 get_the_excerpt and can deliver any kind of excerpt (the real excerpt, a
 customized protected text, a form to give the password etc.)
