[PATCH v2 0/3] pre-push hook support

Main changes since the initial version:

 * The first patch converts the existing hook callers to use the new
   find_hook() function.
 * Information about what is to be pushed is now sent over a pipe rather
   than passed as command-line parameters.

Aaron Schrab (3):
  hooks: Add function to check if a hook exists
  push: Add support for pre-push hooks
  Add sample pre-push hook script
