As Jonathan mentioned, this should probably be taken out of the commit
message because it doesn't reflect what the code actually does. What it
actually does took me a second to figure out. You're marking packed_git
as "private"...well C has no notion of private vs public fields in a
struct so it might be difficult to keep that convention, it also took me
a second to realize that it was only in the scope of packfile.c where it
was ok to reference it directly. Maybe it'll be ok? If we really
wanted something to be private we'd need it to be an opaque type
instead, which may be out of the scope of this code refactor.
