Only allow fast-forward merges in the component repositories when doing
git-pull. This makes it possible to spot problems (i.e. rewriting of
history) in the component upstream . Also, this change prevents the
creation of local-only merge commits in the component repositories.
These merges cause "last_revision" field of the combo-layer config to
point to a git commit that is only present in the users local component
repository but nowhere in upstream.
