Not that you probably need more random cases of C code, but I happened
to be looking at a diff in git.git today, b333d0d6, which is another
regression for the compaction heuristic. The indent heuristic here gets
it right.

Coincidentally, another example is the final patch in this series.

So I am already happier even without digging further yet. :)
