As much as I like indentation as syntax, and am amused by this bug, I'm
not sure we can chalk it all up to space-vs-brace. After all, who would
have wanted two goto's in a row even with braces? It's not like there's
some engineer at Apple who meant for the code to read like this:
if ((err = SSLHashSHA1.update(&hashCtx, &signedParams)) != 0) {
goto fail;
goto fail;
}
This looks to me like a poorly handled merge conflict maybe? I wonder
if we'll ever get the details.
