The way I see it, the core of the problem is that the way you handle
partial re-fontification of a multi-line `union' construct has
a dead spot.
More specifically, if you have code like
1 union
2 {
3 foo,
4 bar
5 }
you can handle fontification from 1,3, or 4 but not from 2. You need to
refine the system you use to keep track of whether we're within
a `union' so that it knows that position 2 is also "within a union".
