[PATCH 0/2] Fix spurious conflicts with pull --rebase

[Elijah Newren <newren@gmail.com>]

This patch series fixes git pull --rebase failing to detect if "local"
patches are already upstream in cases where the upstream repository is
not itself rebased.  Also in the non-rebased upstream case, this
series avoids checking/applying more patches than needed (i.e. avoids
having rebase work on commits which are already reachable from
upstream).

It would be nice to make 'git pull --rebase' able to detect if patches
being applied are already part of upstream in cases where the upstream
repository has been rebased.  As far as I can tell, that would require
changes to format-patch to allow it to be told what 'upstream' is, and
some changes to git-pull.sh/git-rebase.sh to pass it this information.

    --rebase
  pull --rebase: Avoid spurious conflicts and reapplying unnecessary
    patches
