You can add those properties "manually" from the font-lock-keywords.

You can also set the font-lock-multiline property so as to tell font-lock to
try and add this property automatically: if a font-lock keyword's match
extends over more than one line, font-lock will then add
a font-lock-multiline property over the whole match.

I don't have much time for it right now, but I'll keep it in mind,
