Fix a long-standing bug that could cause the wrong index file to be used when committing to the git-annex branch, if GIT_INDEX_FILE is set in the environment. This typically resulted in git-annex branch log files being committed to the master branch and later showing up in the work tree. (These log files can be safely removed.)
