Subject: Make tests pass with recent git (1.7.0 and up).
X-Git-Tag: v1.7.11-rc0~176^2~22
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/349a70d5cf127222c8a089f116070614ebd18732?ds=sidebyside

Make tests pass with recent git (1.7.0 and up).

It seems that in older versions, --message="" was interpreted as "use the
default commit message" instead of "use an empty commit message", and
git-subtree was depending on this behaviour.  Now we don't, so tests pass
again.
