[PATCH 00/14] git p4 branch handling fixes

[Pete Wyckoff <pw@padd.com>]

There are multiple oddities in how git-p4 treats multiple
p4 branches, as created with "clone" or "sync" and the
'--branch' argument.  Olivier reported some of these recently
in http://thread.gmane.org/gmane.comp.version-control.git/212613

There are two observable behavior changes, but they
are in the category of "bug fixes" in my opinion:

    - p4/HEAD symbolic ref is always created now; it used to
      be created only after the first sync operation after a clone

    - using clone --branch now checks out files; it used to
      complain that there was no p4/master ref

Pete Wyckoff (14):
  git p4: test sync/clone --branch behavior
  git p4: rearrange and simplify hasOrigin handling
  git p4: add comments to p4BranchesInGit
  git p4: inline listExistingP4GitBranches
  git p4: create p4/HEAD on initial clone
  git p4: verify expected refs in clone --bare test
  git p4: clone --branch should checkout master
  git p4 doc: fix branch detection example
  git p4: allow short ref names to --branch
  git p4: rearrange self.initialParent use
  git p4: fail gracefully on sync with no master branch
  git p4: fix sync --branch when no master branch
  git p4 test: keep P4CLIENT changes inside subshells
  git p4: fix submit when no master branch
