That would help, but I don't think it would help in the "fast-forward
from A to B where A is B's parent" case I describe in [1].

My suggestion was:

which can be done by replacing "prune_shallow(0, 1)" in patch 3 with
"prune_shallow(0, !repository_format_partial_clone)", possibly with a comment
that the fast method checks object existence for each shallow line directly,
which is undesirable when the repository is a partial clone.
(repository_format_partial_clone is non-NULL with the name of the promisor
remote if the repository is a partial clone, and NULL otherwise).
