The refspecs specified in the .git/remotes/<remote> on the "Pull: " lines are for fetching multiple heads in one go, but most of the time making an Octopus out of them is not what is wanted. Make git-fetch leave the marker in .git/FETCH_HEAD file so that later stages can tell which heads are for merging and which are not. Tom Prince made me realize how stupid the original behaviour was.
