Test minimal rank computation with merge

  $ hg init rank-repo-minimal
  $ cd rank-repo-minimal
  $ touch 0
  $ hg commit -Aqm 0
  $ touch 1
  $ hg commit -Aqm 1
  $ hg update -qr 0
  $ touch 2
  $ hg commit -Aqm 2
  $ hg merge -qr 1
  $ hg commit -m 3
  $ touch 4
  $ hg commit -Aqm 4
  $ hg log --graph --template '{rev} {_fast_rank}\n'
