Yeah. We simplify the code and make it reuse existing unmarshallers
and make it easier to read, and the line count goes up :-(
Most of the extra code is the due to the structure to hold all the
data we need in the callbacks and is a bit less compact.
That said, I think the new code is a little easier to read.
The biggest value is that we reduce the number of reflog unmarshallers
by one which will save work when we start storing reflogs in a
different type of backend.

The update in error message is also to prepare for the possibility
that we might get a different type of ref and reflog store in the
So that we only generate log messages that refer to filenames in those
places where we are actually accessing files directly.
Thanks. I will resend the patch later with Eric's suggestions.
