Comment (by kovshenin):

 For the kind of data coming through `image_add_caption` negative lookahead
 isn't going to be a performance issue. If the alignment class is first in
 the list (which is usually the case) there won't be a lookahead at all
 because of the lazy quantifier. See [attachment:24225.4.diff]
