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.
