From 0105049958b8f8e97ea06c01b3a0b4e406702a63 Mon Sep 17 00:00:00 2001 From: Ariel Lourenco Date: Tue, 2 Jul 2024 18:09:43 -0300 Subject: [PATCH] Fallback to AppData if XDG_CONFIG_HOME is unset In order to be a better Windows citizenship, Git should save its configuration files on AppData folder. This can enables git configuration files be replicated between machines using the same Microsoft account logon which would reduce the friction of setting up Git on new systems. Therefore, if %APPDATA%\Git\config exists, we use it; otherwise $HOME/.config/git/config is used.
