Thanks.

Simple handler (not regexp), for the group corresponding to the closer 
(what's called a HIGHLIGHTn in syntax-propertize-rules docstring). The 
string "\"/", probably.

I'm not sure. Normally, that helps deal with multiline literals, but 
regexps in JavaScript are single-line. Maybe Stefan remembers.

Or maybe it was a result of confusion: the code deleted in 6cd18349 
includes this mistaken sentence: "XXX: Javascript can continue a regexp 
literal across lines so long as the newline is escaped with \."
