Check that renames are correctly saved by a commit after a merge

Test with the merge on 3 having the rename on the local parent

  $ hg init a

  $ cd a

  $ echo line1 > foo

  $ hg add foo

  $ hg ci -m '0: add foo'

  $ echo line2 >> foo

  $ hg ci -m '1: change foo'

  $ hg up -C 0

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg mv foo bar

  $ rm bar

  $ echo line0 > bar

  $ echo line1 >> bar

  $ hg ci -m '2: mv foo bar; change bar'

  created new head

  $ hg merge 1

  merging bar and foo to bar

  0 files updated, 1 files merged, 0 files removed, 0 files unresolved

  (branch merge, don't forget to commit)

  $ cat bar
