From: "brian m. carlson" <redacted> Currently, we always read a object ID of the current algorithm with oidread. However, once we start converting objects, we'll need to consider what happens when we want to read an object ID of a specific algorithm, such as the compatibility algorithm. To make this easier, let's define oidread_algop, which specifies which algorithm we should use for our object ID, and define oidread in terms of it.
