It's a font-lock bug. Font-lock is documented as being poor on multiline 
constructs, irrespective of many file types which desperately need it. 
But I don't see where this is much worse! What happens is that 
fontification at the point where you are editing can get wrong. Turning 
it off and on again repairs it. I much prefer that, to having the file 
permanently wrong, as it was in the past.

Maybe we could have a timer based re-font-lock of edited sections?
