[Plugin: Easy Excerpt] Problems with auto-generated excerpts

Easy Excerpt plugin has are problems with auto-generated excerpts on following causes:

1. has_excerpt() always false with auto-generated excerpts.

2. ‘excerpt_more’ filter don’t work when auto-generated excerpt length is obtained less than the specified in ‘Excerpt Length’ option, (and the ‘excerpt_more_link’ is missing at output).
This can happen when, for example, post contains a ‘Read more’ insert and text before this insert are fewer than ‘Excerpt Length’.

Solution I propose (and use):

in the easy-excerpt.php replace the lines

113-124

function custom_auto_excerpt_more_link($more) {
	$link = get_option( 'easy_excerpt_more_link' );
	return $more. ' <a href="'. get_permalink() . '" rel="nofollow">' . $link . '</a>';
}

function custom_manual_excerpt_more_link($more) {
	$link = get_option( 'easy_excerpt_more_link' );
	if( has_excerpt() ) {
		$excerpt_more_link = ' <a href="'. get_permalink() . '" rel="nofollow">' . $link . '</a>';
	}
	return $more. $excerpt_more_link;
}

with

function custom_excerpt_more_link($more) {
	$link = get_option( 'easy_excerpt_more_link' );
	return $more. ' <a href="'. get_permalink() . '" rel="nofollow">' . $link . '</a>';
}

and 30-31

add_filter('excerpt_more', array( $this, 'custom_auto_excerpt_more_link' ) );
add_filter('get_the_excerpt', array( $this, 'custom_manual_excerpt_more_link' ) );

with

$excerpt_more_link_filter = ( has_excerpt() ) ? 'excerpt_more' : 'get_the_excerpt';
add_filter($excerpt_more_link_filter, array( $this, 'custom_excerpt_more_link' ) );

Please advise if you find problems when using that solution.
