After the parent commit and some of its ancestors, the only place
commits are being accessed through alternates are in the user-facing
message formatting code. Fix those, and remove the add_submodule_odb()
calls.

s/are in/is in/, since "place" is singular? ("the only place...is in
the user-facing")
