Comment:

 I remember assuming this would work:

 {{{
 has_shortcode( $content )
 }}}

 to check for any shortcode in a content, so I support this feature.

 I would prefer to use {{{has_shortcode()}}} though, instead of a new
 function.

 [attachment:31093.5.diff] adds a support to check if there's any shortcode
 in a text, by using the clever idea from @tyxla, where I simplified it
 with:

 {{{
 if ( empty( $tag ) ) {
     return strip_shortcodes( $content ) !== $content;
 }

 }}}
 Here we're talking about this kind of usage:

 {{{
 has_shortcode( $content );
 has_shortcode( $content, 'gallery' );

 }}}

 In [attachment:31093.4.diff] I updated the patch from @ashfame, in
 addition with the update from [attachment:31093.4.diff], with various
 tests. Here we're talking about this kind of usage:

 {{{
 has_shortcode( $content );
 has_shortcode( $content, 'gallery' );
 has_shortcode( $content, array( 'gallery', 'playlist' ) );  // default OR
 has_shortcode( $content, array( 'gallery', 'playlist' ), 'OR' );
 has_shortcode( $content, array( 'gallery', 'playlist' ), 'AND' );

 }}}
