feature-request: display number for `git log --stat`

[KES777]

While I am rebasing

$ git status
interactive rebase in progress; onto 3d276f8
Last command done (1 command done):
   e ece1d11 Do not query DB if user pass wrong arguments
Next commands to do (3 remaining commands):
   pick f6ba33d Setup error if there is no user with supplied login/password
   pick d6950f0 In case of errors we should render 'error' template
  (use "git rebase --edit-todo" to view and edit)
You are currently editing a commit while rebasing branch 'API_for_frontend' on '3d276f8'.
  (use "git commit --amend" to amend the current commit)
  (use "git rebase --continue" once you are satisfied with your changes)

nothing to commit, working directory clean

I often required to edit files:

    Do not query DB if user pass wrong arguments

It will be handy to display numbers in this case too

The first problem with implementing this is parsing the output of git log --stat, which, like git status, is a porcelain command - their output is not guaranteed to be stable, for example if the path is long it can appear in abbreviated form path/to/.../file.txt. We can use git log --stat --raw to get the more stable output for parsing, which leads us to the next problem: git number was designed to work only with the output of git status.

I don't think you need the help of git number to edit the files changed in a given commit - you can use git difftool for that, with little work. The first thing you'll need is to let git difftool know what your editor is. I think it defaults to vi. This is how you can use git difftool to edit the files changed for a given sha1:

$ git difftool 5ebe75b482e5f3ab91460ce47bbfead2020eb9f9^..5ebe75b482e5f3ab91460ce47bbfead2020eb9f9

If that is too long to type you can make a shell script to reduce the typing, something like this:

$ cat ~/bin/gdt
#!/bin/sh
sha1=${1?need sha1}
shift
git difftool ${sha1}^..${sha1} $*
