When I try reproducing these circumstances locally, that is executing a
"cvs add" and a "cvs commit" of a file on a branch where that file
already exists on trunk, CVS writes an internal representation different
to what I see in your repository for this file.
I'm at a loss to explain how your repository came to be this way, but I
can tell you that cvs2git is faithfully rendering what your repository
says into git.
