The FETCH_HEAD refname is supposed to refer to the ref that was fetched and should be merged. However all fetched refs are written to .git/FETCH_HEAD in an arbitrary order, and resolve_ref_unsafe simply takes the first ref as the FETCH_HEAD, which is often the wrong one, when other branches were also fetched. The solution is to write the for-merge ref(s) to FETCH_HEAD first. Then, unless --append is used, the FETCH_HEAD refname behaves as intended. If the user uses --append, they presumably are doing so in order to preserve the old FETCH_HEAD. While we are at it, update an old example in the read-tree documentation that implied that each entry in FETCH_HEAD only has the object name, which is not true for quite a while.
