Vim script to show git commit diff in vertical split while writing commit messages
" Put this in your .vimrc and whenever you `git commit` you'll see the diff of your commit next to your commit message.
" For the most accurate diffs, use `git config --global commit.verbose true`
" BufRead seems more appropriate here but for some reason the final `wincmd p` doesn't work if we do that.
autocmd VimEnter COMMIT_EDITMSG call OpenCommitMessageDiff()
function OpenCommitMessageDiff()
" Save the contents of the z register
let old_z = getreg("z")
let old_z_type = getregtype("z")
