Subject: git-gui: Add more integration options to citool.
X-Git-Tag: v1.6.1-rc1~3^2~53
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=1e65c6225dea2e15df81f6c91927cb0b8fab443c;p=git.git

git-gui: Add more integration options to citool.

- Make citool return nonzero exit code if it did not commit.
- Add a mode where it does not actually commit and simply
  exits with zero code. Commit message is either disabled,
  or simply dumped to GITGUI_EDITMSG before exiting.
- Add an option to immediately start it in amend mode.

Rationale:

1) Use 'git citool --nocommit' instead of mergetool in scripts.
2) Use 'git citool --amend' to edit commits while rebasing.
