Commit b59b033af3957e0de9a44733e26cbcc7114a4dfb ("gnu: emacs-magit:
Substitute git executable path.") should prevent such a situation from
occurring.

Subject: emacs-magit: path error during commit

Hello, for a long time I've struggled with getting a path error when I
try to do a commit using emacs-magit. Here is an example log copied from
the magit-process buffer:

```
  0 git … add -u -- Genesis/gen_1.org
  1 git … commit --
hint: Waiting for your editor to close the file...
Waiting for Emacs...
*ERROR*: Searching for program: No such file or directory, git
error: There was a problem with the editor
'/gnu/store/dpky3z5844bclhswdk69z90vayy65b58-emacs-27.2/bin/emacsclient
--socket-name=/run/user/1000/emacs/server'.
Please supply the message using either -m or -F option.
```

I find this confusing because
- I can use magit to stage my commits
- In the Magit Group (M-x customize-group magit), the Magit Git
Executable is set to /home/christopher/.guix-profile/bin/git, and that
file does exist in my profile.
- /gnu/store/dpky3z5844bclhswdk69z90vayy65b58-emacs-27.2/bin/emacsclient 
also does exist
- Within emacs, I can run the shell command M-! git commit or M-! git
commit -m "..." and this works fine.

I suspect that emacs-magit might not be properly using the Magit Git
Executable path for this action, but haven't had a chance to look at the
source code yet. Probably this should be submitted as an issue or
support request to emacs-magit, but I have not done so since (on
principle) I do not have a github account, or use google groups.

Here is my system information;
