Merge branch 'mb/remote-default-nn-origin' into pu

When the user does not specify what remote to interact with, we
often attempt to use 'origin'.  This can now be customized via a
configuration variable.

Expecting a reroll.
$gmane/210151

"The first remote becomes the default" bit is better done as a
separate step.

* mb/remote-default-nn-origin:
  Teach get_default_remote to respect remote.default.
  Test that plain "git fetch" uses remote.default when on a detached HEAD.
  Teach clone to set remote.default.
  Teach "git remote" about remote.default.
  Teach remote.c about the remote.default configuration setting.
  Rename remote.c's default_remote_name static variables.

Merge branch 'pc/subtree-add-before-fetch' into pu

Comments?

* pc/subtree-add-before-fetch:
  contrib/subtree: allow addition of remote branch with name not locally present
Merge branch 'gp/forbid-describe-all-match' into pu

"describe --match=<pattern> --all <commit>" ought to mean "use refs
that match <pattern> to describe <commit>; you do not have to limit
yourself to annotated tags."  But it doesn't.  Disable the
combination.

We may want to discard this if jc/describe topic turns out to be a
better idea.

* gp/forbid-describe-all-match:
  describe: make --all and --match=PATTERN mutually incompatible
Merge branch 'po/help-guides' into pu

Give more visibility to "concept guides" to help "git help" users.

  mergetools/p4merge: swap LOCAL and REMOTE
Merge branch 'jk/empty-archive' into pu

"git archive" reports a failure when asked to create an archive out
of an empty tree.  It would be more intuitive to give an empty
archive back in such a case.

Will merge to 'next'.

* jk/empty-archive:
  archive: handle commits with an empty tree
  test-lib: factor out $GIT_UNZIP setup
