[RFC/PATCH v2 0/3] New 'update-branch' hook

Currently it's not possible to keep track of changes that happen to a branch, specifically; when a branch is created and rebased. This patch series aims to fix that.

The last patch is the important one, but in the process of testing this I found out that the GIT_DIR environment variable is not always set, so the hooks (all of them) get confused.

Too many changes since v1 to list them all.

Felipe Contreras (3):
  sh-setup: export GIT_DIR
  run-command: make sure hooks have always GIT_DIR
  Add 'update-branch' hook
