[PATCH v2 00/10] replace: add option to edit a Git object

This patch series comes from what Peff sent in the following thread:

http://thread.gmane.org/gmane.comp.version-control.git/243361/focus=243528

The first 4 patches (1/4, 2/4, 3/4 and 4/4) didn't change since v1. I added 6 more small patches to add tests, documentation and a few small improvements.

Christian Couder (6):
  replace: make sure --edit results in a different object
  replace: refactor checking ref validity
  replace: die early if replace ref already exists
  replace: add tests for --edit
  replace: add --edit to usage string
  Documentation: replace: describe new --edit option

Jeff King (4):
  replace: refactor command-mode determination
  replace: use OPT_CMDMODE to handle modes
  replace: factor object resolution out of replace_object
  replace: add --edit option
