With Phabricator's Arcanist is there a way when you run arc diff and edit the commit message to include a message to reviewers that doesn't end up in the commit message. Something like:
Add some comments
Summary: Adds comments to libfoo and libbar explaining foo() and bar().
Test Plan: No.
Reviewers: dave, john
Subscribers:
Review Message: These are just some comments I had lying around - please check them for technical correctness thanks!
Obviously I don't want the Review Message: to show up in git.
