[aur-general] Why do we use --config-dir ./ in /usr/share/pacman/PKGBUILD-svn.proto ?

Hi all, I'm creating a svn PKGBUILD. I'm behind a proxy, so I set the useful variables in ~/.subversion/server . Why the PKGBUILD template override this location with current dir by default ? Is it bad to drop --config-dir ./ in my PKGBUILD ? Regards, Manu
