Log message:
Various cleanups reported by people using the alpha release.
Incorporate "order-only" prerequisites patch.  Wrote a test for it.
The test shows what might be a bug in the code; I need to look at it
more closely (anyway it doesn't behave as I expected).  Also I haven't
done the docs yet.
