Log ref changes made by git-merge and git-pull.
When git-merge updates HEAD as a result of a merge record what happened during the merge into the reflog associated with HEAD (if any). The log reports who caused the update (git-merge or git-pull, by invoking git-merge), what the remote ref names were and the type of merge process used. The merge information can be useful when reviewing a reflog for a branch such as `master` where fast forward and trivial in index merges might be common as the user tracks an upstream.
