Test for issue2364

  $ hg rm b
  $ hg ci -md

  $ hg up -q -- -2

Test that updated files are treated as "modified", when
'merge.update()' is aborted before 'merge.recordupdates()' (= parents
aren't changed), even if none of mode, size and timestamp of them
isn't changed on the filesystem (see also issue4583).

This test is now "best effort" as the mechanism to prevent such race are
getting better, it get more complicated to test a specific scenario that would
trigger it. If you see flakyness here, there is a race.
