git-validation fails for first commit

[apostasie]

git-validation
git-validation -range=HEAD
git-validation -range=

Will all fail on the first commit (example repo) with:

fa7c1da "Initial commit" ... fatal: ambiguous argument 'fa7c1daeafe58b8a0caa35c05ae8ac9e30188d80^..fa7c1daeafe58b8a0caa35c05ae8ac9e30188d80': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
FAIL
  - FAIL - errored with: exit status 128

I guess there is no parent commit to the first commit ;-)

Oh! good catch.
