Simon Hausmann (8):
  git-p4: Always call 'p4 sync ...' before submitting to Perforce.
  git-p4: After submission to p4 always synchronize from p4 again
      (into refs/remotes). Whether to rebase HEAD or not is still
      left as question to the end-user.
  git-p4: Cleanup; moved the code for getting a sorted list of p4
      changes for a list of given depot paths into a standalone
      method.
  git-p4: Cleanup; moved the code to import a list of p4 changes
      using fast-import into a separate member function of P4Sync.
  git-p4: Cleanup; Turn self.revision into a function local variable
      (it's not used anywhere outside the function).
  git-p4: Cleanup; moved the code for the initial #head or revision
      import into a separate function, out of P4Sync.run.
  git-p4: Cleanup; moved the (duplicated) code for turning a branch
      into a git ref (for example foo ->
      refs/remotes/p4/<project>/foo) into a separate method.
  git-p4: Added support for automatically importing newly appearing
      perforce branches.
