Issue2383: hg log showing _less_ differences than hg diff

  $ hg init issue2383
  $ cd issue2383

Create a test repo:

  $ echo a > a
  $ hg ci -Am0
  adding a
  $ echo b > b
  $ hg ci -Am1
  adding b
  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo b > a
  $ hg ci -m2
  created new head

Merge:

  $ hg merge
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

Make sure there's a file listed in the merge to trigger the bug:

  $ echo c > a
  $ hg ci -m3
