Fwd: Q: use '-C' flag with 'git config --global'

Hi,

I'm running into issue that if I run `git -C <pwd/to/showmax/project>
config --global user.email` I don't get expected email.
Expected: tomas.prochazka@showmax.com
Got: tomas.prochazka5d@gmail.com

My config contains a little catch:

~/.gitconfig
```
[user]
       name = Tomáš Procházka
       email = tomas.prochazka5d@gmail.com

[includeIf "gitdir:~/Workspace/Showmax/"]
   path = ~/Workspace/Showmax/.gitconfig
```
~/Workspace/Showmax/.gitconfig
```
[user]
    name = Tomáš Procházka
    email = tomas.prochazka@showmax.com
```

I get correct email setting if I run command without `--global` flag. But What I understand from the [`git-config` docs](https://git-scm.com/docs/git-config#_description) if no flag is passed the values are read from system, global and local.

If I run commands one by one, No returns the ~correct~ expected email:

~ $ git -C <pwd/to/showmax/project> config --system user.email ~ $ git -C <pwd/to/showmax/project> config --global user.email tomas.prochazka5d@gmail.com ~ $ git -C <pwd/to/showmax/project> config --local user.email

Am I missing something? Thanks for the answer.

Regards Tomáš Procházka
