Bug: [redbean] Fetch() HTTP client ParseHttpMessage error on big headers

[elitepleb]

What happened?

Another Fetch() error that errors out on an input that is one longer than the previous.
In this case, 1286 writes Good!, 1287 writes Bad! and triggers an early exit in ParseHttpMessage
This broke an internal tool when updating to the 3.0 release.
As requests after authentication would fail, but only in specific cases.

.init.lua test case

function OnHttpRequest()
        if GetPath() == '/headers' then
                SetHeader('padding', string.rep('a',1287) )
                Write('Hello world!')
        else
                result = Fetch('http://127.0.0.1:8080/headers')
                if result then
                        Write('Good!')
                else
                        Write('Bad!')
                end
        end
end
