From a4a94c2774355fdd15d2eafe99daf193855999bc 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.
