Error handling could be improved

[huayra]

When translating "error" from 3 to 4 is kind of broken. It works fine as long as you do not something like the URL or the Hostname. I.e. in vcl_recv:

• error 404 "Not Found";
• return (synth(404, "Not Found"));

but, this example does not work (req.http.host would not work either):

• error 751 "http://" + req.url;
• return (synth(751, "http://")) + req.url;

as we should expect:

• return (synth(751, "http://" + req.url));

We understand this as a syntax error that can easily be fixed. Would you welcome such an addition?

I thought I fixed this. 😞

Feel free to submit a PR if it's still happening.
