Hello Alexandre, I saw on emacs-devel that patches against vc-git.el should be directed to you. I interact with some git projects, but I do not leave the MinGW-git in my PATH. Thus, I need to be able to tell Emacs where to find git. The other vc elisps used a defcustom named vc-${vc}-program, so I named the git one to follow their convention. Thanks for your time, -- /v\atthew
