[PATCH v1 0/4] 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

I added the following fixes:

- add "strbuf_release(&result);" in import_object(); this was suggested
  by Eric Sunshine
- use MODE_LIST instead of MODE_DELETE if no arguments are passed; this
  makes the test suite pass
- add "--no-replace-objects" when calling "git cat-file" in export_object();
  so that we edit the original object if an object is already replaced

I am not happy with the fact that if the user doesn't modify the object when editing it, then a replace ref can still be created that points to the original object. I think something should be done to avoid that.

Once that is fixed, I plan to add some tests and documentation, but I wanted first to let you know that I am looking at this.

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