I'm using git. I already created a Differential for my HEAD commit, but I updated it to fix review comments and changed the summary in the commit message. The commit already has "Differential Revision: D123".
I do "arc diff --edit"
It asks to interactively edit my commit message, but the message it presents to me is the one from the website, it completely discarded my commit message. Is that intentional? What I want is to update the summary on the website by using the one from my git commit. Is that achievable?
