If the situation is a file that had a branch tag added to it after the
branch was first created, then there is a git commit corresponding to
that event that consists of the addition of that file with no history.
This commit might also include the addition of other files to the
branch, but should not include any file content changes.
It seems to me that in your case such commits could be "grafted over":
E.g., if "C" is one of these special manufactured commits, then you
could use git grafts to change the parent of "D" from "C" to "B", then
bake in the change with "git filter-branch". This would make C
inaccessible and subject to garbage collection.
But please check by hand to make sure that this makes sense; for
example, it could be that other branches in the neighborhood make the
