The reason is the relative size of the code. I could do it the other
way but then
the changes that is moving the code would be much bigger.
Moving it like this, by first renaming it to refs-be-files.c and then
moving the backend agnostic parts back
is that the backend agnostic parts are mostly helper functions that
are independent of eachother.
This makes it possible to move just a few functions at a time making
the individual changes smaller and easier to manage when there are
A lot of the code that implements the actual files implementation for
refs storage implements the ref-cache/ref-dir/packed-refs/loose refs
This is all code that is intertwined and is difficult to split up.
Thus almost forcing me to move the whole 3000 lines of implementation
in one single monolithic patch.
I think "first rename, then move the agnostic parts a small section at
a time" was the least bad solution.
