Sometimes it's useful to edit the commit message before arcanist commits a change. Example situations include:
* Fixing typos
* Updating the description to account for changes during review
* LLVM-specific: 'Depends on D1234' is considered undesirable in commit messages and so these must be removed.
While this is possible via the Differential web interface, it would be useful to be able to make these edits from Arcanist.
I've been using a small patch that adds a --edit option to 'arc commit' to provide this feature for about a year. Now that Imagination has signed the corporate CLA I'm able to contribute it. Is it ok to submit the patch to differential?
