[PATCH v2 0/4] Add --graft option to git replace

Here is a small patch series to implement:

        git replace [-f] --graft <commit> [<parent>...]

This patch series goes on top of the patch series that implements --edit.

The changes since v1 are the following thanks to Eric, Junio and Peff:

- change commit message of patch 1/4
- added patch 4/4 that was previously sent separately
- in patch 4/4 rename the existing grafts file
  into grafts.bak
