When a commit is compared against its parent, we want to show the
complete commit message as new in the diff screen (diffing the commit
message of the viewed commit with the commit message of the parent
commit does not make sense). To detect this case PatchListLoader sets
the againstParent flag.
Until recently we only supported comparing commits against the first
parent and hence the againstParent flag was only set if a comparison
against the first parent was done. Consider all parents now.
