Support @NamedQuery auto-completion and syntax-highlighting when query is broken across lines

Currently, the auto-completion and syntax-highlighting for @NamedQuery annotations works great, but only if the entire query is in a single-line string. On a daily basis I deal with queries that are almost never under 200 characters in length. This makes writing queries on a single-line extremely awkward. However, as soon as I break any part of the query to a new line, I also break Hibernate's annotation processing. So I'm looking for the best of both worlds here - syntax highlighting when the query is split across an arbitrary number of lines.
