When git-merge sees that we are on an unborn branch (i.e., there is no
HEAD), it follows a totally separate code path than the usual merge
logic. This code path does not know about verify_signatures, and so we
fail to notice bad or missing signatures.
This has been broken since --verify-signatures was added in efed002249
(merge/pull: verify GPG signatures of commits being merged, 2013-03-31).
In an ideal world, we'd unify the flow for this case with the regular
merge logic, which would fix this bug and avoid introducing similar
ones. But because the unborn case is so different, it would be a burden
on the rest of the function to continually handle the missing HEAD. So
let's just port the verification check to this special case.
