Description
The first line of commit messages in Go follows a convention, with some quirks like omitting src/ in the go repo, and using filenames for things in the repo root, etc.
I think it should be possible for git-codereview to filter through the changed files and suggest / prepopulate a prefix when the commit message doesn't have one, similar to how it adds a change-id footer if there isn't one.
