No, no fantastic magic.  But in some cases, together with
font-lock-syntactic-keywords, it's a good way to get "multi-line keywords".
Other examples: verbatim envs in LaTeX, heredocs in sh-script, things
like that.  I also had a hack that marked strings with a missing \ at the
end of the line using this trick, but the behavior had some rough edges.

This trick is of restricted applicability, of course,
