So what I suspect is happening is that topgit is trying to set HEAD to
"refs/top-bases/whatever". Aneesh, can you confirm by running your test
with GIT_TRACE=1?  I suspect you will see a call like "git symbolic-ref
HEAD refs/top-bases/foo".

Actually, I was able to reproduce with the recipe from Martin and Bert
elsewhere in the thread. And that is indeed what is happening:

  trace: built-in: git 'symbolic-ref' 'HEAD'
  'refs/top-bases/test'\

Thanks, Jeff, for the accurate analysis. Since I do not see a way
for topgit to do things differently -- top-bases are *not* heads and
thus warrant a different namespace -- can I assume that this is to
be fixed in Git and not in TopGit?
