OK, I've got you now! It sounds like jit-lock perhaps isn't really the
right strategy for mark-up modes. But it seems like a hook is required
in the jit-lock stealth bit. This is surely needed as _well_ as the
after-change hook that expands the region, not instead of it.
For example, if a change were the insertion of a ">> .... <<", the region
to fontify would include some text before the new insertion. The
after-change-expand-region hook would detect this by using information
recorded by a before-change-function. AWK Mode uses this stragem. A
stealth-expand-region hook would scan back to the ">>", and stop.
