REVISION SUMMARY
  This adds a transaction summary callback that reports the number of
  new orphan, content-divergent and phase-divergent changesets.
  
  The code for reporting it is based on the code from the evolve
  extension, but simplified a bit. It simply counts the numbers for each
  kind of instability before and after the transaction. That's obviously
  not very efficient, but it's easy to reason about, so I'm doing this
  as a first step that can make us quite confident about the test case
  changes. We can optimize it later and make sure that the tests are not
  affected. The code has been used in the evolve extension for a long
  time and has apparently been sufficiently fast, so it doesn't seem
  like a pressing issue.
  
  Unlike the evolve extension's version of this report, this version
  applies to all commands (or all transactions run as part of any
  command, to be exact).

  Any idea why this introduced failures on Windows?  The missing orphan line I assumed was a #if conditional, but there's not one in any of the files.

  That one actually looked correct (i.e. it seemed wrong for it to be missing in the Linux case). It seems to have something to do with cache invalidation. I'll continue digging. Thanks for bringing it to my attention.
