Try modifying the git-pull script; change the last line from
  eval "exec $eval"
to
  echo "exec $eval"
.

Is the output of the form
  git-rebase --onto XXXX YYYY
or
  git-rebase --onto XXXX XXXX
?

With cf65426de, and from what I'm guessing from your description, I'd
expect the latter.  And, I'd assume the latter is equivalent to
'git-rebase XXXX', but you say that's not the behavior you're getting.
 Finding out which of my assumptions is wrong may help you debug the
issue.
