Comment (by azaozz):

 As we are excluding strings from texturize:
 - It seems we don't need to match `[[shortcode]]`, it's enough to match
 `[shortcode]`. The extra [ ] are unaffected by texturize.
 - Following the same logic we don't need to match `[/shortcode]` and
 `</tag>`. There is nothing that needs excluding from texturize in there.
