Git configuration using conditional imports

It is possible to include a git configuration for a particular context (directory, branch name...). For example, override the username and email in a directory and all its subfolders.

# ~/.gitconfig
[includeIf "gitdir:~/workspace/perso/"]
    path = ./.gitconfig_perso
# ...
# ~/.gitconfig_perso
    name = Steven DUBOIS
    email =

Now, when I work in the ~/workspace/perso directory, my username and email match the values in .gitconfig_perso config file.
