[PATCH 04/10] commit: move resolve_ref() closer to where the return value is used

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

resolve_ref() returns a static buffer and the value may change if
another resolve_ref() is called. Move resolve_ref() closer to printf()
where the value is used to reduce that chance.
