Subject: builtin-commit: fix amending of the initial commit
X-Git-Tag: v1.5.4-rc2~3^2~2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=d616a2396456fdb6679efa0c0bee301aeb606ca8;p=git.git

builtin-commit: fix amending of the initial commit

When amending initial commit without editor, the command
incorrectly barfed because the check to see if there is anything
to commit referenced the non-existent HEAD^1.
