I presume you don't use the font-lock-extend-region stuff because you need
it to work with Emacs<22, right?

Huh?  In which circumstance do you see a need for such a setting?

Hmm...wait... my crystal ball here tells me that you forgot to set the
font-lock-multiline property from your font-lock-keywords.  is that right?
Please read the discussion about multiline and font-lock in the latest Emacs
manual (it's been significantly improved, so it should help, and if doesn't
help enough, then we should improve it more).
