Disable USE_SYMLINK_HEAD by default
Disable USE_SYMLINK_HEAD by default. Recommend using it only for compatibility with older software. Treat USE_SYMLINK_HEAD like other optional defines - check whether it's defined, not its value. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
