Subject: Always pass a sha1 for the initial parent so that git-fast-import doesn't think
X-Git-Tag: v1.5.3-rc0~65^2^2~108
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=f9162f6a4cc9f4af3e527412b364a8eda4502920;p=git.git

Always pass a sha1 for the initial parent so that git-fast-import doesn't think
it's creating a new branch from itself. It's a sensible error in general but
in the case of incremental imports we have to apply force :)
