Comment (by azaozz):

 I'm not sure this is a good idea. Why would we want dashes in shortcode
 attributes, what (critical) problem is solved with that?

 The shortcode regexps are pretty big/slow already, making them even more
 complex is undesirable imho. Also, imagine the billions of times this
 slower regexp will run every day. Is it really worth the extra kWh of
 electricity for the servers so we can have slightly fancier attribute
 names (that few would ever use)?
