Your gut feeling is a good one!
See the following typescript. You'll notice that the new files created in wc2 pushed and pulled get merged into the first wc at the wrong location, and index and working dir get out of sync. This only happens when I export GIT_DIR in git-sh-setup. Ouch.
Arguably, this is a bug in git-merge though!
