That won't help.  I decided this was a good opportunity to learn about
'git bisect run', and bisected it to 1c7b76b (Build in merge,
2008-07-07).  This was with bad = 47a765d (pulled from Shawn's repo
this week) and good = v1.5.6.

In case you want to check my logic, the commands are below.

* Setup:

  mkdir $temp_repo
  cd $temp_repo
  git init
  echo foo > foo
  git add foo
  git commit -m initial
  echo a > foo
  git commit -m a foo
  git checkout -b side HEAD^
  echo b > foo
  git commit -m b foo
  git checkout master

* Bisection script:

-- 8< --
#!/bin/sh

rm -rf $temp_repo/{bin,libexec}
make -j3 prefix=$temp_repo install

PATH=$temp_repo/bin:$PATH
cd $temp_repo
touch foo
git merge side
test -f .git/MERGE_HEAD
s=$?
git reset --hard
if test $s != 0; then
    echo did not work
    exit 1
else
    echo worked
    exit 0
fi
